The Walking Dead
Breaking bad is one of the greatest shows of all time ONE of them and arguably better than the wire. Breaking bad can sometimes be slow and the charachter development for the female charachters is nonexistent. Despite this Breaking Bad hooked me in from the start with it's interesting premise and with it's amazing plot. Walking dead was very good at first but then started to drop in quality bit by bit then the ending was just very bad. But despite this I still love Walking dead. Breaking much better though with its interesting premise amazing plot and it action. It also is just amazing a king fall right before you eyes.
both shows are great but the sopranos would be best.
This is a biased vote as I have yet to see Breaking Bad. My knowledge of Breaking Bad stems from Screen Junkies' Honest Trailer and from what friends have told me.
