I agree! When I first saw him on there I was really skeptical, but as time went by I really warmed to his dark side. He's doing a fantastic job!
Oh and best scene of the season: Dexter loses it completely and drags Arthur off his son into the kitchen!!! DH and I were yelling at the TV and sitting on the edge of our seats. And then who the reporter turns out to be!
I don't want to give any major spoilers so that's all I'm saying, but DANG! This is the best season.
