I recently watched this dark comedy called Cooties. It takes zombie movies in a completely different direction. The virus outbreak is started by children eating chicken nuggets, made from infected chickens. Due to the fact that the virus only infects prepubescent kids, it's called cooties.
Elijah Wood is hilarious and extremely awkard in this film. Rainn Wilson is a comedic hero. Wilson telling Woods' charcter that He's running around like a hobbit is classic. The blood and gore effects are very well done. Overall, it's one of the best dark comedies I've seen in a long time.
