This kind of blows, especially if they just left people hanging like that.
I didn't really watch a lot of episodes in season 4, but during season 1 I was glued to the TV, season 2 wasn't bad either. I think I slowly started to lose interest after that. I hated how they would just suddenly cut out characters/storylines, sometimes with no explanation, too. Kind of like they'd just kill the character when they didn't know what to do with them anymore. 24 was also using the same formula for a while.
Oh well, I guess. It was nice while it lasted.
