Oh, so much richness to enjoy. Buffy burning down the dance hall is hilarious (she does seem to have a pattern going there with dances); Martha's bravery is preserved in spades; and, up until this very last scene, the Weeping Angels are never 'seen' onscreen and yet still pull off their creepy assassination technique. They get you when you're not looking...

It's a brilliant premise well and beautifully executed. Very nicely done.
