What interests me in this series, among many other things, is that there are not many sympathetic characters. We root for Walt because he has cancer, but he really has turned into an evil person. Skyler, on the other hand, is just trying to take care of herself and her children, but comes off as the bad guy because she is annoying and the opposite of Walt.
We shouldn't like Hank because he's working against Walt, but I sure as heck do. Hank's a great character. We also shouldn't like Marie because she's crazy and a thief, but I'm partial to her as well.
