I enjoyed Power of the Doctor, and I think it helped that Legend of the Sea Devils was bad and lowered my expectations haha. There's no doubt that this episode totally pandered to Who fans, and I absolutely enjoyed those bits. The rest of the episode wasn't too bad, the plot was a bit of a mess but it was a fun mess!
Chibnall's era was by far my least favorite showrunner, and that became very noticeable when I randomly rewatched an old episode of Series 2. The early series had a good grasp on having small moments with interesting side characters that stuck with me (like Lady Cassandra being told she was beautiful for the last time), whereas Chibnall never really did that. It was a lot of big ideas that had characters responding to them.
ANd so with that, Jodie's era is done. Barring a cameo in the next few specials for the 60th for reasons. And well, she's just not my doctor. She never left any real impression or felt Doctor-ey enough. I don't know what element was missing but... something. But I know she's got fans and will be some people's first, so... she wasn't BAD but I don't think I'll ever be revisiting it.
At this point I'd be fine if they did away with the Doctor numbering. I know it's not going to happen since the fandom will certainly carry it on, but getting new people into the show can be tough when they hear a Doctor referred to as 13 and thinking they have 12 other Doctors to know beforehand. And that's before even getting into the technicalities. And thinking they need to watch previous seasons before starting current ones. Heck I still have to remind myself that NuWho really isn't new!
Instead of numbers they could colloquially be called the Scarf Doctor or Bow Tie Doctor or whatever.
I think Jodie's Doctor may have had the same problem as Peter Davison's. She was just too pleasant and bright and noble. And yeah, the Doctor is certainly all those things, but the Doctor also has something of a dark side to them, and I think the best iterations of the Doctor realize this. With Jodie I never really got that sense very much.
I've always liked the complexity of when Doctors explored this, but I also think it's still possible to be pleasant, bright and noble and still be a great character. The problem is, the writers/producers don't know how to make it work within story conflicts. The next best example I can think of is (well-written) Superman, where there's tons of stories with him not embracing a dark side and still being interesting.
But ultimately, we didn't get that with 13 Much like @desa said, 13 almost feels like a watered-down Doctor. Like if an AI watched all of Doctor Who and made a script for an episode, haha: Do an exposition dump, while saying a quirky thing here and there.
Part of me suspects they wanted to play it safe with the first female Doctor, especially with her first season, which is why it's so bland, with a few great episodes. The downside to playing it safe is that you don't get a character that really sticks out and… ugh. I really, really wanted to like her more. I hate to say the clichéd thing, but I'm looking forward to Big Finish working with her and taking her character in more challenging directions.
I was surprised by the characters from old who in this episode. Felt more like a love letter to who then a goodbye to that specific era. Made me wonder if that was the 60th.
Likely because this was the Centennial special, in celebration of the BBC's 100 years. Not that everyone was expected to know that though, the marketing for this episode was horrid.
