It's back for Season Three.
It's darker and less comic these days. The plotline with the younger character; "Jesse" is really captivating right now. A brilliant story, heartbreakingly well-acted by Aaron Paul.
From an interview with Bryan Cranston:
The term "breaking bad" is a southern colloquialism and it means when someone who has taken a turn off the path of the straight and narrow, when they've gone wrong. And that could be for that day or for a lifetime. And Walt is that kind of guy. He's never even gotten a parking ticket, he's always done things the right way. It's not until these dire circumstances are presented that a decision needs to be made. He has the weight of regret on his shoulders and it's suffocating him. But the last thing he wants to do is put his family through this hardship of taking care of a dying man, he still dies anyways and he leaves them penniless. That's the personal legacy he leaves for them and he couldn't allow that to happen. And it's from that point that he makes this decision and goes on that journey. It's an impulsive decision. It's an emotional one. He's backed into a corner. It's not a pragmatic or practical decision. He is putting the blinders on, and knowing that if he really thought about it he could talk himself out of it, and justifiably so. He decides to make this bold, desperate move out of the set of circumstances he's given. The way I look at it, that's the only way he could make that decision.
