Basically, I loved it.
It wasn't perfect, by any means, and the plot was very paperthin. But I enjoyed the performances, the emotion was definitely there and the interaction between 1 and 12 is simply wonderful, I could've watched the two of them go at it for hours on end.
Four things I disliked, though: Clara's appearence was awfully obviously greenscreen. Why not have there? The preview of the Doctors to come for One, was dissapointing. Once again the Genesis of the Daleks clip for Four, an awful amount of Five, and I didn't catch any Six, Seven or Two. And way too much of the Warrior, honestly. Twelve's final speech was, frankly, too long and too meta. Its obviously Moffat talking, and I appreciate the reference to the Doctor's name (a plot point for so many of his stories with Eleven), but it was simply too long-winded. And finally, the regeneration itself seemed lite compared to Ten's.
But beyond those nickers, I enjoyed it enormously. Brilliant! And damn if I won't miss the Twelve Doctor....
