Can't speak for anyone else, but I find it to be very well acted, and it just strikes kind of a creepy chord with me. Getting to see the actual serial killer all throughout the show and his sick little rituals, trophies, and how he goes about his life trying to keep it all a secret is fascinating. I actually don't care for the other storyline, with the coked up hookers and everything, at all. I think its forced and doesn't fit with the feel of the rest of the series, but I'm only on episode 4 or so.
