Okay, I think I'm done reviewing this season. I remember previous seasons being mediocre and I even didn't watch the end of the third season, but I don't remember a season with this many boring ideas. Maybe Brian showing up and Dexter going full-on serial killer will change things, but I'm not confident about that.
I don't even want to comment on the rest of the episode, but I have a question. Did the writers include Ryan's theft of the Ice Truck Killer's hand earlier in the season solely so we'd remember who Brian was when he did pop up? I actually wouldn't be surprised if they did, given their continuing incompetence.
