I also wasted my time reading "Toms" review and I wish I hadn't cause that might have been the dumbest review I've ever read.
Anyway, I thought the movie was great. I was pleasantly surprised and it was surprisingly moving. It's intense, unnerving, and also very human. It was never really what I expected.
It's less a film about zombies and more a film about a kid facing a very human experience that happens to take place in a zombie apocalypse.
