Do watch Chuch, it is good. Moonlight is sort of similar to Angel, minus Angelus and without the vamps being automatically evil. The first episode reminded me QUITE distinctly of the first episode of Angel.

I think they did a werewolf show a couple of years ago and it flopped like a fat man into a swimming pool. Elves would be interesting though. I don't think we've had an urban-fantasy elves TV show.
