I would say there is a decent amount of violence, but honestly I think this movie could get passed off as a pg-13 movie. There is no gore that should bother even children that are fans of slasher movies.
Profanity
Mild
Alcohol, Drugs & Smoking
Moderate
Wine drinking, as well as cigarettes, but in one scene the youngest looking woman looks to be rolling up a marijuana cigarette, and the killer smokes from some kind of a pipe. The pipe was made to look like it could have been a crack pipe, but I don't know enough about that type of drug to say for sure.
Frightening & Intense Scenes
Moderate
I would say that this movie would be considered frightening or intense to children, or to those that are bothered by slasher movies, but if you are a fan of slasher movies this movie will most likely be a disappointment.
