The Happening

Parents need to know that this tense horror film is the first one from writer-director M. Night Shyamalan to earn an R rating -- and for good reason. It's loaded with violent, bloody images and is much more graphic than the PG-13 movies that have earned him a following among teens. It revolves around people falling victim to an airborne toxin that induces suicidal behavior -- consequently, there's a constant stream of self-inflicted deaths throughout the film, many of them quite graphic (falling from heights, gunshots, car crashes, heads going through windows, etc.).
