This is a great movie with an awesome twist. My concerns for younger viewers watching this movie is the violence. There are many murders, most of them are off screen and only implied but you do get to witness a brutal stabbing that takes place behind a white sheet. The charaters are silhouetted but the blood splatters everywhere. Language is another main concern. F*ck is used four times, B*tch is used twice and sh*t is used once. The word t*ts is also used when referring to a womens chest. A conversation also takes place stating that Santa is not real because they caught dad putting the gifts under the tree. In conclusion, this is a great movie for adults but not for kids.
