I agree that there hasn't been much of a threat to Dexter at all (though, given how lax he has become in his methods in the past 2-3 seasons, there should
be). Still, I think season six has the edge over season five -- which is not to call either particularly good, mind you. I'm ready to get this finale over with, although I probably won't be able to see it until January, due to holiday travel.
Does that Michael C. Hall interview address criticisms of the show?
