I really like this movie. Some of the effects are simply crappy, true. The zombies themselves, though, do look decent. And the dialogs are pretty funny if you're into that kind of humor. If you don't think it shows humor that the heroes ponder whether they're dealing with classical "Romero" zombies or the new viral "sports" zombie type, then this movie is not for you. Otherwise, you're probably going to have some good laughs in this movie. I had. Other than the gags, the dialogs are surprisingly good for a B-movie and witty throughout, the actors aren't as bad as I had expected either. And the ultra-bad CG effects somehow aren't that distracting, they somewhat add to the feeling of watching a comedy, willingly or unwillingly, I don't know.
Worth a rent.
