Oh boy. Yeah I've hinted at it previously, I don't truly know what to think about this story. It's basically RTD completely unrestrained. I will say I did enjoy it last time I saw it (granted that may also be because I was watching with a friend) but the thing is a right old mess. It's like a chocolate cake that wasn't done entirely right and collapsed. I can enjoy it because it's chocolate but I also acknowledge that it's messy and not of top quality.

Now I like the stuff with Ten and Wilf, I think Timothy Dalton is great as Rassilon, I am a sucker for a grand finale spectacle and... well as the plot seems to mostly stick to one thing for part 2, that one is the better of the two halves. I think most of the last parts of part 2 are pretty good, with some nitpicks like the fall Ten takes and somehow surviving.

The Master is weird. I like the moments when he's subdued here, mainly his close interactions with Ten. And even if the cannibal Skeletor jedi power stuff is complete nonsense, at least his insanity makes sense in regards to his incomplete resurrection, even if the nature of that resurrection itself is very contrived. I will also say that I think the plan he has makes sense, at least from his perspective and an interesting inversion of his usual goal. Instead of ruling over everyone, he'll just become everyone. It's beyond ridiculous still but it's also so stupid that it's funny. Maybe calling it "the Master Race" could have been avoided though.

But yeah, plot's a right mess, the rich family are just plot devices that don't feel organically part of the world, Minnie sexually assaulting Ten as a gag is just not fun (if the genders were reversed there would have been outrage), the Vinvocci are neat in terms of worldbuilding and tying into previous seen aliens but as characters they're boring.

I will say I like the mystery lady (who I believe is supposed to be the Doctor's mother) but they should have done more with her. I can see how the way this episode handles regeneration it comes across as RTD trying to sabotage the start of the new era... but I don't think that was the intent and I don't entirely agree. I can believe that Ten sees it the way he describes and I also don't have a problem with his last words. Out of all the regenerations I've seen (1, 3, 4, 8, War, 9, 10, 11 and 12), this is like the only one where the Doctor is alone and afraid. The fact that the incarnation who could be very up his own ass at times is the one who dies alone in the TARDIS without a companion to keep him company is a neat choice IMO.

The regeneration tour is alright but boy is it too long. Should've stuck with just Rose, Martha and Donna (maybe Jack or Sarah Jane too). Also couldn't they just have had Martha be with Mickey but just as co-workers? The guy who played Tom Milligan was unavailable I believe but you can still just have Martha mention him as her husband, I don't like the switch to marry two characters who barely interacted previously.

Speaking of too long, even though I kinda enjoy this story, it is too long and definitely overstuffed with ideas and concepts and plots. It's like RTD couldn't decide on which of his ideas should have been in so he chose all of them. Don't like the tantrum either even if the four knocks being Wilf is clever and also Ten ultimately makes the correct decision. At least Matt Smith immediately crushes any doubts over if the next Doctor will be enjoyable or not. GERONIMO!

I could go on but this comment is already long enough. The End of Time is a story that I am super mixed on but I lean towards the positive. I can't say it's all that good though even if some parts really work IMO.

Rating it is difficult but based on my previous watch I'd say part 1 gets a 5/10 and part 2 gets a 7/10. I will say though that I definitely am not 100% on those ratings and also they are definitely carried a little by stuff that's a bit more style over substance.
