Only four reviews so far as I write mine. Looks like you either hate this episide or really enjoyed it. I was happily freaked out by it and think it was the best episode of the season. Better, even, than Dollhouse because of the unique, bordering on taboo subject matter. Get over the necro part. Hello, this is a horror show!
The rest of the story plays on feelings we all have in dark times; alone, rejected, like a freak (for whatever reason), like no one will ever understand. In the end this episode is an old fashion romance with grande gestures (sans a boombox). I thought it was fun! Eh, the wedding scene was a little over the top, but all in all I say great story.
