Logan, were critically acclaimed and did very well at the box office. Others, like X-Men: The Last Stand and X-Men: Apocalypse were underwhelming (to say the least). But despite the mixed results, the studio kept producing new entries at a steady clip and all of them were successful on a commercial level.

Nearly two decades since the original X-Men helped kick off the golden age of superhero cinema, an era is about to come to a close. With Disney's acquisition of 20th Century Fox's entertainment assets now official, the X-Men franchise will eventually be rebooted as the characters are integrated into the MCU. But first, Dark Phoenix looks to send the series off on a high note. Unfortunately, the polar opposite happened and it looks like Fox saved the worst for last.

It's worth mentioning that there are a plethora of Dark Phoenix reviews still to be published. a definite reflection of its poor reception), meaning the verdict has come in. The Dark Phoenix score may fluctuate a few points (in either direction) as more reviews come in, but it will probably stay in the 20s.

This is a sad turn of events, as a landmark film franchise (the first X-Men came out two years before Sam Raimi's first Spider-Man) fizzles out instead of having a triumphant ending. Even though this was the last installment in the current Fox continuity and was something of a lame duck from the start, fans and everyone involved with the production still wanted Dark Phoenix to be a satisfying sendoff. There's no telling when the mutants will make their debut in the MCU, but hopefully when they do, the results are much better than Dark Phoenix.
