Quarantine is an aolmostly shcokingly effective, scary and intense horror film that the faint of heart and weak of stomach should definitely skip. But, that's not to say that it won't appeal to teenage horror movie fans as much as adult fans, because it will. Now, what makes Quarantine so heart-stoppingly intense and brutal to watch is the fact that it all feels so real. It is one of those found-footage films, and definitely one of the better ones out there in the genre (especially when you consider that this film came out about a year before the Paranormal Activity film did), and a lot of the claustrophobia just adds to the overall effect of them, and even more surprising is that the cast, headlined by Jennifer Carpenter, actually all do a equally very good job at conveying an absolutely palpable sense of fear and terror, and that it pretty much literally holds you right there in your seat until the films final reel. Yeah, it's that good. But, this film is Rated R and there are a few things that parents should definitely know and be made aware of before they even think about letting there children watch this movie: There is frequent strong horror violence and gore, including some very disturbing images of terror, including many people being shot repeatedly, a young infected child being brutally beaten to death on screen with the actual camera used to film the entire movie (!), along with other very gruesome shots of infected people chomping on the survivors, ripping there throats out and otherwise mutilating them. Also prevalent in the film, is frequent profanity, including uses of sh-t, f--k, hell, a--h-le, g-dd-mn, d-mn and more. So, if you are a big horror fan like me, and you enjoy the found footage genre, than I think that you should definitely check this awesome horror movie out. Reccomended.
