I just can't understand the people that say they don't like Walt. I guess if you immerse yourself as one of the characters in the show then maybe, but I think his transformation has made this show great. I can't simply hate any of the characters for their personalities, as it all adds to the show and works brilliantly together. If Walt was your friend, then sure, I can see not liking him, but he is an incredibly deep character who has done the "Mr. Chips to Scarface" transition perfectly.
This also kinda goes along with how some people say that Mike should have killed Walt when he had the chance. Well, if that did happen, there goes the show. Again, maybe I don't immerse myself totally into the show and only look at it as a show. Maybe someone can help me understand the other viewpoint on this?
