Meh, Dexter. I don't really know what it's supposed to be-- a comedy or a thriller, but it's a pretty big fluke in both departments, imo. It's as you said, Satan: an intriguing concept ruined by annoying characters.
Yeah. The women in the show are pretty much all super annoying. And I found myself wanting Dexter to get caught towards the end as well. Still really enjoyed season 2 though.
