V I am on the fence about. Yes, you'd have to watch season 1 in order to appreciate season 2. I think there were 12 episodes or so. It was getting good near the end but I didn't *love* it (like I loved Lost and am currently obsessed with True Blood).
Did you watch BSG? Not that you would need to to watch Caprica. It's one of those shows that is so "smart"...it makes me feel dumb sometimes.

Love it! Very involved - not a light show at all. BUT I think it might get cancelled. They have filmed I think 18 episodes, 9 of which were shown earlier in the year and then they will show the last 9 starting sometime this fall. That's what I understand anyway.
I'm going to check out Haven. There are tons of shows I've loved in the past but as for what is coming up or still currently on...I don't know so much. (We don't have cable.) I had been hearing Fringe is very good now. But I think it's in it's 3rd season?
