I take back every bad thing I've ever said about [very lightly spoilery (click to open)]the Supernatural books and meta episodes because if it weren't for them, we wouldn't have this. And I love it so much. I loved it from the brief and beautiful "Then," all the way to the end. I had such low expectations - I didn't even watch it until lunchtime on Wednesday - and I'm just bowled over.
I've got no idea how I'm going to drabble it, though. :-/
