Warning! This review contains spoilers for Doctor Who season 15, episode 8.

Doctor Who concludes another season, and, frankly, this is potentially the most wild ending of any season in the entire history of Doctor Who. "The Reality War" sees Ncuti Gatwa's Fifteenth Doctor face the Unholy Trinity — the Rani, Conrad, and a baby — that makes wishes come true. However, only about half of the episode deals with this plot, as the final half concerns itself with the Doctor trying to track down his "daughter," Poppy.

The Rani wants to create a new race of Time Lords with the help of Omega. However, her plan backfires when the mad god Omega finally arrives and eats her whole. Following this, the Doctor easily banishes Omega before trying to restore reality and keep his daughter alive. To make this happen, he ultimately needs to begin regenerating to release the energy needed to pull everything off. The final moments reveal a shocking twist that is utterly baffling.

Doctor Who Has Absolutely Lost The Plot

It might come at the end of the episode, but it's clearly the biggest moment of the series: Ncuti Gatwa's Fifteenth Doctor regenerates into Billie Piper, aka former Doctor Who companion, Rose Tyler. The final credits don't appear to confirm Billie as the next Doctor, but these events (on the back of two bi-generations in two seasons), David Tennant appearing as the Fifteenth Doctor, and all the other ups and downs of the RTD2 saga are truly astonishing, and not in a good way.

Don't get me wrong, I adored Billie Piper as Rose, and I think she is a very capable actress, but in the world of Doctor Who, what is actually going on?

Doctor Who is supposed to be a whimsical, wacky, and fun show, but as a sci-fi series with such a long legacy, it's a little bit wild to see all of that unraveled to descend into utter madness. Don't get me wrong, I adore Billie Piper as Rose, and I think she is a very capable actress, but in the world of Doctor Who, what is actually going on? The cameo from Jodie Whittaker was lovely, but it's somewhat overshadowed, as is everything else, by that monumental reveal.

The pacing of the episode is not atypical for a special extended finale, with much of the setup from the previous episode being resolved in the first 30 minutes, but the final half of the episode follows the idea that the Doctor needs to save his child — who isn't his child — but since he and Belinda believe it, it is. There is a fine line between clever and ridiculous, and I think the line has been crossed occasionally in RTD's latest era. Ultimately, it just seems senseless, silly, and too outrageous.

The Rest Of The Episode Is Just Kind Of OK

Early on, seeing Anita appear and help the Doctor, and the time hotel being a key to restoring normality, the episode was on a brilliant track. The discourse between the Doctor and the Rani, and the confrontation between the Rani and Mel is also fun. There are some clever moments and some solid development, though it all moves slowly. The special effects were disappointing despite a larger budget, but the action remained fun.

It's one of the most bizarre and goofy episodes of Doctor Who to date.

Beyond this, the episode starts to feel a little circular, with the plot falling into odd directions until the conversation between Ncuti's Doctor and Jodie Whittaker's — a bright spot in the episode. It doesn't make a lot of sense, but compared to the rest of the finale, it's not an issue. This dialogue is fun and sets things in motion for the Doctor's regeneration.

But despite a few good moments, this may be the weakest episode of the season, and one that ends on such a massive and surprising cliffhanger that seems like it's only there to hook audiences enough to return. The fact that Gatwa's Doctor — who's been so great this season — regenerates into Rose is so odd and disappointing. And, with the way that RTD has attempted to explain other plot points, it feels like the explanation for the regeneration will be flimsy. Whatever happens, it's one of the most bizarre and goofy episodes of Doctor Who to date.
