I'm going to be that guy and just say there was nothing wrong with Season 2. All that drama and crap was what's expected when it's the god damn apocalypse and someone is god damn pregnant and you're getting kicked out of the only safe place you think you'll ever find, soon and almost everyone in your group as at each other's throats.
Sure it's about the zombie apocalypse, but it's not always going to be about shooting zombies and trying to be a badass. I like the realistic approach the comics and show take.
Anyways really looking forward to tonight's episode. From the promos, and reading the comics - I, along with some others - know this Season is going to be really grim.
