Chomp: As zbinks pointed out, Worst Case Scenario was the film that I mentioned which is what spawned Frankenstein's Army.
I watched it over the weekend. It was decent. It's a found footage film, so some may be turned off right there. I was a little annoyed that they went that route at first but I found the build pretty effective. I'm not sure the payoff worked all that great, but it was still entertaining.
The zombies are all the ones we've seen in the Worst Case Scenario promos, but somehow they come off a little goofy when presented this way (found footage).
