Huh? I Don't Get It
So, they didn't like the old man at the beginning, and thought he was too "strict," because he was killing the zombies? Why? What were they supposed to be doing, giving them hugs and feeling sorry for them? That doesn't make any sense at all.
I think the whole "I can't shoot Jimmy Bob Sue" thing is way too cliche by now. Obviously, the zombies aren't people any longer, and they are dangerous and have to be destroyed. Clearly, too, the former people would probably would not have wanted their bodies to be allowed to reanimate, walk around like that, and endanger people.
I'm still not all the way through this movie, but this one thing really annoyed me and seemed really PC and whiny.
