Damn, that was a great ending!
Sure, yes, some of it was a little ropey and wordy and, yes, there were flaws, but overall I loved the last three episodes, not least for the fact that even the Timelords are terrified of the Doctor, even more so than of Rassilon!
To borrow a line from Pratchett: “Sergeant Colon was lost in admiration. He'd seen people bluff on a bad hand, but he'd never seen anyone bluff with no cards.” All the Doctor has is his reputation, but that's all he needs and you *really* don't want him to be angry with you...!
So we get to the end of the universe, but we still don't find out who the Hybrid is. Is it Who? Is it Me? Is it Him and Clara? Who knows? (Or does he?!) There's got to be more to come on that story...
Meanwhile, some other great in-references, him possibly being half human, four knocks, telepathic mind-wipes, reversing the polarity, and I also loved the touch of the Diner seeming to the same one that he meets Amy, Rory and River in. Was that one actually a Tardis in disguise? Who knows, but never mind :-) plus a great line from the Doctor when asked if he'd been travelling? "Yeah, from time to time..."
Finally, of course we have, Run, You Clever Boy, Run, but this time he doesn't Remember...
Some people may not like it, some may sneer and bitch, but I loved it and that's all that matters!
