Like many others I just finally caught up to real time with Breaking Bad. My wife and I watched from season 1 to half way through season 5 in about 2 months and it's quickly become our favorite show.
Not only is the acting and writing top notch but the directing, editing and cinematography is fantastic. You just don't get television shows of good movie quality very often. Character arcs like these (for basically every character) are something you just don't see on TV very often. Aaron Paul is awesome. The only thing I don't really like is Walter White Jr. He seems to overact on a fairly regular basis.
