Yeah, Dexter would be a flop with Hall's acting. I love supernatural due to Dean. His one liners are damn funny. If you have seen the recent episodes you would remember this :
Sam: So what, you think Batman is raping those girls?
Dean:He does carry a rage dude

I like the spoof episodes they make in supernatural. This season already had 2 spoofs. One on Twilight that was "Live free or Twi-hard". There were a lot of comments about the movie. Like, there was a pic of A vampire watching a girl whil sleeping on the cover of a book. So dean said" Dude, he's watching her sleep, hows that not Rapey?"

.Or when Dean was about to cry in a emo scene, he said to himself, "Damn, I'm pattersoning."
Other Spoof episode was on X files, "The truth is in here"

I saw the trailer of Cape on Youtube, looks interesting.

I'm sucker for superhero based tv shows
