Pretty good season premiere. Looking forward to more Tyreese, Michonne seems more likable, Beth is all hardened to the world now, alcoholic D'Angelo Barksdale could be interesting.
The idea of the prison being plagued by some non-zombie related illness is interesting (I'm assuming that's where they're headed).
The show has always had a lot of potential that it's struggled to live up to in the past, so we'll see how the season shapes up. The current showrunner has worked on some of the show's better episodes, so I hope he sticks around.
