I know S4 is already in progress (there are short videos on YouTube showing a few behind-the-scenes clips), but I don't have it in me right now to watch and mourn the loss of what the first two seasons developed (and what S2 destroyed).
I will be suffering through S4 (I know... I don't know why I'm doing this), but I don't plan on watching anything prior to the premiere. I already know plenty of ways this could go south, but I don't want to think about it for too long.
