If you are looking forward to a scary thriller/horror, youwould be dissapointed. If you were loking forward to a well-made sci-fye adventure with some spooky and funny parts, you would love it, there is quite a lot of cursinng, and a small amount of drug use, including a man offering to sell pot to a teenager, but it is all played for laughs. the voilence is thrilling and startling, people got eaten(not graficly showed), blood splatered on the window of a bus when the alien killed a bad guy, and a bloody man, thought to be dead, reached his bloody hand out at the kids, then threatened them with a gun to run away, explosions etc. occur, though no good guys were killed, some footage of a zombie in a video the kids made was slightly disturbing but quite hokey. The kids are loyal to their friends.
