Ok, so I finished season 2 last week. Fantastic, and very unexpected. But what does it mean? (SPOILERS!!!)
To be honest, I was kind of hoping that Walt is turning into a straight up bad guy. Not unlike what happened to Vorenus in the second season of Rome. I think that would be an interesting direction to take (and they sort of tease with it), and I think it would be fun to watch Walt turn into a legitimate drug lord. Maybe we'll eventually get there, I don't know.
With respect to the finale: What. The. Fuck. What does it mean? Is the sky falling for Walt? Was it a deliberate choice for Walt to be wearing a pink sweater when the pink bear dropped into his pool? Does this mean Walt has passed the point of no return... that is to say, there's no going home for him? I'm surprised no one has been discussing this.
