The dialogue and the acting is probably the best part of the show. I have never watched a show where every character was terrific. Mind you, those Latino twins got on my nerves but besides them, the main characters along with the supporting ones are terrific.
The dialouge, although brilliant every season, was pretty top notch season 4. Walt along with Gus are battling for the top spot of ultimate bad ass.
I LOVED the twins! They were a nice contrast from everyone else. Never spoke but spoke with their actions.
