I freakin' loved it, every bizarre, fascinating minute, and can't wait for Part 2.

The Guardian was also highly impressed. Not much I can add to that.
Buffy fans will spot the typo in the 'Best Lines' section - Annie did actually say, "There was a werewolf called Nina in Buffy too. But I stopped watching after I started, y'know, living it." And, of course, Nina was in AtS but I guess they used 'Buffy' as a catch-all for both shows since that's the more familiar name in pop culture.
Speaking of Buffy, anyone else feel a sense of deja vu when Daisy and Ivan turned up? Makes one wonder if Toby Whithouse is a BtVS fanboy. *g*
