I've never been much of a horror-comedy fan. It's not that I've thought they were all that bad, I just found most of them more scary than funny. This one, however, I am happy to say, delivers. It's very funny. One or two parts just had me in stitches they were so hilarious. However, that said, there's a lot of content here that parents might be worried about. The violence is the most obvious one. The first ten minutes are gorier than the rest of the film, because they show zombies taring chunks of flesh from people in various places. There's a lot of gunplay, and there are some squibs used, so it looks like blood is flying everywhere. Also, the zombies' make up itself makes them look frightening, most have blood on their mouth and whatnot. The sex is limited to a zombie stripper running down the street in hopes of eating her clientele. This is done mostly for comedic effect and it is actually a lot more funny in the film than it sounds on paper. There's also a few sex references, but none of those are really all that bad. The language is about average for an R rated feature. About a dozen f-words, as well as other, milder swear words. There's also another thing that they didn't have a "concern" descriptor for that makes this film less appropriate for children. There's this eerie feeling throughout the film that what is happening in the film is not only completely plausible (which, obviously it isn't), but also imminent. I think its the realistic-sounding story about a mutation of mad cow disease that makes it seem so frightening and will have you looking over your shoulder when you hear a noise, as well as looking at whoever you're watching the movie and thinking "What if they're already infected..." All in all, I say this is okay for fourteen year old horror movie fans and sixteen year olds otherwise.
