The sad thing here is that even the liberal choir this movie is trying to preach to is going to feel embarassed at the ridiculously broad strokes this flick paints. It's got hippies, stoners, gays, muslims, rednecks, and so on and so forth. All are caricatures with no weight behind their presence because they are poorly acted and badly drawn.
Want a sample of the dialogue? How 'bout this ill-conceived pun battle - "I really like your Iraq." "Well there's Norway you're getting into these panties tonight." It's even more painful watching it, although I will admit this scene did save itself a bit by having a zombie subsequently rip the boyfriends face off.
Basically the only thing that made this insufferably self-important waste of time watchable after the first 10 minutes was amusing myself by creating the simplest drinking game in the world to play along with it. Just drink everytime some overused liberal cliche is spouted out in a manner so ham-handed that supporters of the point are embarassed by it. I promise you'll be obliterated in no time.
Props to the f/x squad though. Those were tight, if generally unimaginative barring a few notable exceptions. Beyond that, save yourself the pain and skip this at all costs.
