I watch Grimm. Nick is pretty, but also mildly boring. He's a solid character for what they need him to be right now, we'll see if he develops as the show progresses. I like Monroe a lot, though he is often used as an expositional plot device. He does have some of the best lines (him and Sgt. Wu) and he's also a vegetarian!! I am also *very* fond of Captain Renard, but that could just be because of Sasha Roiz, since Renard's kind of a jerk when he's not pretending to be super upstanding police chief guy.
I think there's been a massive increase in popularity of fantasy/sci-fi/urban fantasy media these days. Part of it, I think, is that our special FX capabilities are so advanced that you can get realistic alien/fantastical imagery - there's no longer that "B-movie" cheap feel to things anymore. The genres are also becoming more mainstream, maybe the fact that "geeks" are making more money and thus influencing businesses to cater towards them makes these genres more acceptable and easily accessed for "non-geeks"? The use of fairy tales as a starting point is likely to combine the urban fantasy thing with a world that most audiences are familiar with - it's quicker to use things that are already in our culture than having to explain an entire new world and mythos to an audience.
I always wonder about people who say they "love" animals, but continue to eat meat. If that's your idea of love, I question what sort of twisted world view you must have.
