Damn, I liked the show. It started a bit rough, but got really good by the time the second season ended.
I wished they didn't cancel it after the season ended, though, so it wouldn't end in a fucking cliffhanger. Then again, maybe you shouldn't end in a cliffhanger if you aren't guaranteed to come back (although I know it's a deliberate strategy).
Cardinal Biggles, I'd still recommend watching it - just stop before the final five minutes and you'd be set.
ETA: There's talk of making it into a movie
, but I'm not optimistic. They apparently had put a lot of thought into the third season, though.
