First off, watching the opening scene I get even more pissed off at the fact that the writers think Carl not only finding Shane and Rick pretty far away from the farm, but doing it at night time is a believeable scene.
Secondly, that scene where Rick told Lori that he killed Shane and Carl finished him off, I couldn't stop laughing after she did that evade move when he tried touching him. So hilarious, quality acting & writing. Even thinking about it now makes me laugh. Oh you silly woman, I hate you and your offspring. She is such a shit mother it's unbelievable, in the middle of the zombie invasion she goes 'OH SHIT WHERE IS CARL?"
I had honestly hoped to see more people die than possibly the most unimportant characters in any show ever. I honestly have no idea what the two died were called or what their relationship with the farm residents was, couldn't care less either. Wish they had some fecking balls and killed someone like the old bald woman or Andrea. We all know that when she eventually finds the group again she'll go on her stupid whining trips and talk about how they abandoned her and how she should have believed Shane.
The drive-by-shooting-zombies scene was silly as well. I really, really, really didn't get that. WHY!? Surely driving around not only wastes gas but also makes it incredibly hard to hit the zombies in the head, which they presumeably hope to do. For some reason they are all master shots though, especially the Korean kid who worked as a pizza delivery guy pre-zombie-outbreak can easily hit a zombie straight in the head when sitting in the window of a car driving around a bumpy field, mhm.
Possibly the most exciting thing about the whole season was the end, that sword lady with the zombie slaves and that big prison looks promising.
Anyway my advice for the decision makers, sack everyone involved, start the third season pretending season two and the farm never happened and release an apology campaign like the BP one:
