The dream sequence stuff overstayed its welcome.
I understand what they were trying to do but I wasn't feeling it. I would have rather have seen the much more of the aftermath. It seems like they were inspired by that episode of The Sopranos after Tony was shot and started to dream of an alternate reality as a traveling salesman while in a coma.
Overall, it was the most solid season yet and definitely deserves more recognition as a show. Season 4 will be here before you know it so it's interesting to see where it all goes.
