This! I can't believe I wasted so much time catching up on the last 4 seasons of Dexter. They had no idea what the **** they were doing with such potentially great story archs. I hope someone someday does a remake of Dexter s4 on.The Breaking Bad episode indicates just how smart Gilligan & Co. are about knowing how much they can needle at Walter White’s morality, then pushing him exactly that far so the audience realizes the full weight of everything the man has done. The show works because of its great acting and fantastic plotting, sure, but it’s also successful precisely because it has a very clear view of its main character.
