The MCU X-Men movie tantalizingly close to bringing in a whole new era for the beloved Marvel characters.

The X-Men movie timeline is all over the map in of quality, although the best X-Men films also rank high among the greatest superhero movies ever. Even within the genre they helped redefine, the X-Men films stand apart. The original X-Men film introduced an ensemble cast led by Patrick Stewart and Ian McKellen and a fully-formed superhero team before Wolverine received his first spinoff in 2009; this is the opposite of the MCU's method of solo superhero films building up to The Avengers. With the rise of the family-friendly MCU and the DCEU, the X-Men franchise's R-rated spinoffs were met with critical and box office acclaim, though not every movie fared so well.

The New Mutants (2020)

The New Mutants Superhero Movies 2020

While The New Mutants was a movie that held a lot of promise and a solid cast roster, ultimately its potential did not come to fruition. What was seemingly intended to be a brave new foray for the X-Men franchise - exploring the teen horror genre - instead came across as lackluster on both a narrative and tonal level, resulting in one of the franchise's least popular films, and most widely criticized as well. This reception can be seen in the movie's box office results, which saw it gross $49 million worldwide - a total thought to be between $18-31 million less than its budget.

Though having a core roster of characters who were less tied to the overarching X-Men movie landscape raised the potential for a fascinating spinoff series - and one that audiences didn't need to have seen hours of prior releases to totally understand - this also meant that the film was placed in a more precarious position wherein it needed to start more from scratch with its cast and story. Unfortunately, this meant the failure of the movie were more pronounced, as it seemed even further away from what audiences had come to expect from a live-action X-Men movie.

This lead to the movie's most damning criticism, which was that it came across as generic, instead of fully embracing its unique comic roots. As such, it's perhaps for the best that the MCU X-Men introduction brings a fresh start for the Marvel team after the subpar reception to its final non-MCU installment.

X-Men Origins: Wolverine

Wolverine's CGI claws in X-Men Origins Wolverine

X-Men Origins: Wolverine was the first stand-alone spinoff, which was intended to be followed by X-Men Origins: Magneto. Directed by Gavin Hood, X-Men Origins: Wolverine adapted Marvel Comics' Origin miniseries, which revealed Wolverine's real name - James Howlett - and his tragic past. Hugh Jackman became a producer and trained hard to sculpt Wolverine's muscular physique while Liev Schreiber was cast as Sabretooth, Logan's half-brother and arch enemy. The film rewrites history so that Wolverine and Sabretooth fought in the Civil War, both World Wars, and in Vietnam, and depicts how Logan entered the Weapon X program to have adamantium grafted to his bones.

The script by Game of Thrones' David Benioff and Skip Woods is convoluted and crammed with mutants, with Taylor Kitsch miscast as Gambit, while Hood's shaky direction results in a bewildering (Logan has CGI claws) and simply bad film. One of X-Men Origins: Wolverine's greatest sins the portrayal of Deadpool, which left Ryan Reynolds so dissatisfied, he successfully campaigned to make a proper Deadpool movie. Meanwhile, the bad taste in fans' mouths left by the one-two punch of X-Men: The Last Stand and X-Men Origins: Wolverine forced the entire franchise to reboot with X-Men: First Class in 2011.

Hugh Jackman will return as Wolverine in Deadpool 3, but there are a few blemishes on his nine prior Wolverine performances in the X-Men movies.

X-Men: The Last Stand (2006)

Brotherhood in X-Men The Last Stand Ian McKellen as Magneto and Vinnie Jones as Juggernaut stood side by side

X-Men: The Last Stand was directed by Brett Ratner, who replaced Bryan Singer when he left the franchise to make Superman Returns for Warner Bros. Written by Simon Kinberg and Zak Penn, X-Men: The Last Stand follows up Jean Grey's death in X2: X-Men United by cramming together two different comics stories: Joss Whedon's Gifted, about a mutant cure, and The Dark Phoenix Saga, which was relegated to the B-plot and stripped of most of its resonance. The Last Stand also infamously features the murder of Professor X by Jean Grey and the death of Cyclops, who died offscreen.

In fairness, Hugh Jackman, Ian McKellen, and Famke Janssen try to inject as much humanity as they can to the material but Ratner's cookie-cutter direction and frantic pacing zips through the pivotal story beats, robbing nearly everything of its impact. X-Men: The Last Stand introduced Ben Foster as Angel and Ellen Page as Kitty Pryde but gave them little to do, and the film drew groans for dialogue like Vinnie Jones' terrible quip, "I'm the Juggernaut, b*tch!" In spite of a few bright spots, X-Men: The Last Stand earns its infamy as the worst of the mainline X-Men movies.

X-Men: Apocalypse (2016)

Oscar Isaac in X-Men Apocalypse with Storm and Psylocke behind him

The final X-Men movie directed by Bryan Singer, X-Men: Apocalypse attempted to replicate X-Men: The Animated Series on the big screen. Oscar Isaac portrays En Sabah Nur, the 5,000-year-old all-powerful mutant called Apocalypse, who awakens in 1983 and tries to destroy the world. It was never really clear what Apocalypse's plan actually was as he assembles his Four Horsemen - Storm (Alexandra Shipp), Angel (Ben Hardy), Psylocke (Olivia Munn), and Magneto (Michael Fassbender) - but X-Men: Apocalypse goes for broke with large-scale cartoony action as the X-Men combine their powers to fight Apocalypse while nuclear missiles threaten to wipe out the planet.

Singer hired young actors to portray the core X-Men as teenagers, including Sophie Turner as Jean Grey, Tye Sheridan as Cyclops, and Kodi Smit-Mhee as Nightcrawler. The film teases Jean's eventual corruption by the Phoenix Force within her, which sets up Dark Phoenix, while Jennifer Lawrence spends as little time as possible in Mystique's blue makeup. Hugh Jackman also cameos as Wolverine as he violently escapes from the Weapon X facility. After the success of a similar sequence in X-Men: Days of Future Past, Apocalypse repeats a superspeed rescue by Quicksilver (Evan Peters) as the X-Mansion is destroyed. Ironically, a meta-joke that "the third film is always the worst" ended up applying to the overlong and bombastic X-Men: Apocalypse.

The Wolverine (2013)

The Wolverine and Yukio

The Wolverine is the second standalone spinoff about Logan directed by James Mangold from a screenplay by Mark Bomback and Scott Frank. It adapts the 1982 Marvel Comics miniseries Wolverine, but it's also a sequel to X-Men: The Last Stand where Logan still mourns Jean Grey's death as he's called to Japan by his old World War II friend, Ichiro Yashida (Haruhiko Yamanouchi), who runs a corporation threatened by the Yakuza. The Wolverine strips Logan of his mutant healing factor for most of the film, leaving him more vulnerable than ever, and he also meets one of his major comic book love interests, Mariko (Tao Okamoto). However, Wolverine has more on-screen chemistry with his sidekick Yukio (Rila Fukushima).

Despite the intriguing Japan setting and Mangold's attempts to make a grittier movie, The Wolverine devolves into cartoony schlock by the end when Logan faces the Silver Samurai, a giant robot. In a post-credits scene set "two years later", Logan runs into Magneto and an inexplicably alive Professor X, setting up X-Men: Days of Future Past. The Wolverine was a big improvement over X-Men Origins: Wolverine and the potential for Mangold's future glory to come - Logan - was evident.

Dark Phoenix (2019)

Jean Grey is overwhelmed by her powers in Dark Phoenix

Dark Phoenix is the second attempt at adapting The Dark Phoenix Saga comic story, but this time, Jean Grey's corruption by the Phoenix Force is the A-story that tragically fractures the X-Men. Writer Simon Kinberg steps into the director's chair for what turned out to be the final Fox X-Men film after it was purchased by Disney. In Dark Phoenix, which is set in 1992, the X-Men go into space for a rescue mission when Jean Grey is imbued with the otherworldly Phoenix Force. Jean's leveling up in power shatters the psychic barriers that Professor X placed in her mind when she was a girl, which causes Jean to rampage and forces the X-Men to try to stop her, resulting in a tragic death. Dark Phoenix also introduces Genosha, which is Magneto's island refuge for mutants, and Jessica Chastain plays a mysterious alien who tries to manipulate Jean and the power of the Phoenix.

Dark Phoenix had highly-publicized reshoots resulting in its release date delayed twice, and it now has the lowest Rotten Tomatoes score of any X-Men movie, but it's also not the disaster many claim it to be. Sophie Turner explores the darkest corners of Jean's mind as she transforms into the powerful Dark Phoenix, which culminates in a different and surprising outcome from X-Men: The Last Stand's. The film also asks intriguing questions about the cost of Professor X's dream of humans no longer hating mutants and whether he was right to manipulate young Jean's mind to shield her from childhood trauma. Ultimately, Dark Phoenix serves as a somber finale for the overall X-Men saga, despite its interesting ideas and strong performances from the cast.

X-Men (2000)

Professor Xavier about to enter Cerebro in 2000's X-Men

X-Men, directed by Bryan Singer and written by David Hayter, kicked off the modern comic book movie boom period in 2000. While it's a modestly-scaled superhero adventure, especially by today's standards, X-Men introduced the iconic frenemies Professor X and Magneto played respectively by Patrick Stewart and Ian McKellan, the concept of superpowered mutants hated and feared by humanity, and it marked the debut one of the greatest superhero castings ever: a then-unknown Hugh Jackman as Wolverine. X-Men also cast James Marsden as Cyclops, Famke Janssen as Jean Grey, Halle Berry as Storm, and Oscar-winner Anna Paquin as Rogue, while Ray Park played Toad, Tyler Mane played Sabretooth, and Rebecca Romijn was unforgettable as Mystique.

The plot involved Magneto's attempt to kidnap Rogue and create a machine that would turn the world's leaders into mutants, but X-Men's true superpower was how it focused on the characters, using Wolverine and Rogue as the audience's POV into the dangerous world of mutants. X-Men is often derisively ed for Storm's quip (scripted by Joss Whedon) about what happens when a toad is struck by lightning. However, X-Men's emphasis on depicting the mutants as flawed and conflicted proved the Marvel Comics formula worked on the big screen.

Deadpool 2 (2018)

X-Force prepares to parachute in Deadpool 2.

Directed by David Leitch, Deadpool 2 doesn't match the shock value of the original film but it's even more ambitious. Deadpool 2 not only brings in Cable (Josh Brolin) and X-Force but also the concept of time travel, which Wade Wilson indulges in during the film's end-credits scene. Deadpool 2 controversially kills off Morena Baccarin's Vanessa as Cable arrives from the future to kill Wade's young friend Russell Collins (Julian Dennison), who will one day grow up to become Firefist and kill Cable's family.

Deadpool assembling X-Force, consisting of Bedlam (Terry Crews), Domino (Zazie Beetz), Shatterstar (Lewis Tan), Peter (Rob Delaney), and The Vanisher (Brad Pitt), and how most of them are instantly killed off is one of the film's inspired highlights - as is Wade using a time machine to kill the version of Deadpool in X-Men Origins: Wolverine and prevent Ryan Reynolds from starring in Green Lantern. Colossus Stefan Kapičić) and Negasonic Teenage Warhead (Briana Hildebrand) return from the first film and Deadpool 2 also includes a comics-accurate version of the Juggernaut. A PG-13 cut titled Once Upon A Deadpool was released in Christmas 2018.

X-Men: First Class (2011)

X-Men First Class

Directed by Matthew Vaughn, 2011's X-Men: First Class is a soft reboot of the mainline X-Men films and depicts not only the first gathering of X-Men but the origin of the lifelong friendship and animosity between Charles Xavier, Magneto, and Mystique (incorporating elements from the canceled X-Men Origins: Magneto). Set primarily during the 1962 Cuban Missile Crisis, X-Men: First Class also introduced the Hellfire Club, led by Sebastian Shaw (Kevin Bacon), and their designs on world domination. Vaughn's film broke from the standard superhero genre and embraced the period's Cold War setting to create an engaging superhero spy film about the X-Men, with an impeccable cameo by Hugh Jackman's Wolverine.

Despite the daunting task of recasting the iconic mutant lead roles, James McAvoy and Michael Fassbender successfully embodied the rowdier younger versions of Professor X and Magneto. Meanwhile, the X-Men franchise scored Jennifer Lawrence to play Mystique right before she became a superstar thanks to The Hunger Games films. Vaughn's snappy direction mixed superhero action with a classic James Bond sensibility that reinvigorated the X-Men franchise for the next decade where X-Men would now have to compete with the Marvel Cinematic Universe and the DC Extended Universe.

Deadpool (2016)

Ryan Reynolds in Deadpool costume in 2016 Fox film

An R-rated, raunchy superhero comedy, director Tim Miller's Deadpool was an unexpected breath of fresh air for the X-Men franchise. Produced by and starring Ryan Reynolds as Wade Wilson, the titular Merc with a Mouth, Deadpool was actually in development even before Reynolds portrayed an inferior version of the character in X-Men Origins: Wolverine. After years of campaigning to properly bring Deadpool to the big screen, Reynolds was thankfully proven right when Deadpool and Deadpool 2 became the highest-grossing X-Men films worldwide.

In Deadpool, the red-clad mercenary breaks the fourth wall as he narrates his own origin and misadventures. Instead of using top-name X-Men in the film, Deadpool scores by including a comic book-accurate version of Colossus. Meanwhile, the sullen Negasonic Teenage Warhead steals scenes and instantly became a fan favorite mutant. Despite the violence and debauchery, Wade's romance with Vanessa (Morena Baccarin) feels genuine, and Reynolds gleefully makes Hugh Jackman's Wolverine the butt of several clever jokes.
