I wanted to like it. I really did. I tried to like it. I never laughed, though. The corny interjected graphics were silly and done. The rest of the jokes seemed to be "I'm the opposite of my outward appearance. Laugh at me!" And I sincerely hope they weren't trying to surprise us by revealing that Buck was actually Tallahassee's kid. That was pretty obvious the first time he said it, puppy video or not. If I was hoping for anything going in, it was more of the zombie kill of the week stuff, and less uninspired buddy film. Yeah, I understand that was the point, but maybe that's mine--even the plot was tired. In the first five minutes you know they're going to end up tripping off family style into the sunset.
Contrast this with, say, Night of the Living Dead (my all time favorite zombie movie)--it's still a character story. Everyone feels genuinely frightened. Out of all horror movies I've ever seen, it just feels the most realistic. They have no idea what's going on. Scientists don't know. The local fuzz thinks they have everything under control. No one can accept the risen dead are zombies. And human tension runs high in the house, culminating in the murder of one of the survivors by the others, the BBQ of the young couple, and Barbara rushing out into her brother's arms. That's a good character driven zombie story to me.
