I liked Day Break. I know I don't understand network economics, but they had a whole TV series completed, but they decided to end it halfway through in order to show reruns of George Lopez. I'm saddened that reruns did better ratings than Day Break.
Anyway, I've realized, watching through season 3 now, that I actually liked Season 2 better than 3. In season 2, only Charlie's flashback bored me (because I don't really care about the baby anymore). In season 3, I'm on episode 6, and the only flashback I haven't fast forwarded through has been Eko's.
