It is too hard core, and cant last long without ruining the integrity of the story. breaking bad has at most 3 more seasons left. I am sure they wont go the way " LOST went and made the extra 2 seasons which ruined the show for the next 30 years. if lost stopped and just left everything open one cared what was going , the show would of lived for another 20 years..
Sopranos was one of the best 20 shows of all time. They danced the last season on storyline of uselessness. I personally loved the last scene because it pissed so many people off. It goes to show how much are involved in the show when they go to black and there are 1000 different endings people come up with
