Is this better than The Wire?
I don't think it is. I'll agree with Macphisto that the premise is more original than in the Wire, but that's about where it stops for me. You could even argue that the Wire's exploration of crime in Baltimore from so many different perspectives is much more original than anything in Breaking Bad but that's not entirely fair. For one thing, Breaking Bad is an ongoing series and we haven't seen its conclusion yet. For me, the Wire is a complex essay on society, written in a rich vernacular. I don't think Breaking Bad has much to say about society as a whole.
Don't get me wrong, I'm a big fan of Breaking Bad and I think it's definitely worth watching. It has, for the most part, excellent writing, acting and directing. I think the story drags at times but that's a minor complaint, mostly prompted by the fact that when the show gathers momentum, it is very very enjoyable. I can easily say that it's one of the best TV dramas out there at the moment.
