Watched it for the first time on Sat. Pretty good. My only complaint is that it's "one of those shows" where they don't provide you with all the information to figure out what's going on, then pat themselves cleverly on the back that they pulled one over on the viewer.
I really liked the characters, so that's probably enough for me to tune in for a few more episodes. I also like the semi-humorous style, but judging by the preview for next week, that's not a constant theme.
Oh, and since I'm not British, a lot of what they say (Danny in particular) goes right over my head or I can't understand it (too fast). I've the same complaint with Dr. Who.
