Saw V (R, 2008)

Parents need to know that this "torture porn" horror movie is full of graphic, grisly violence that combines sadistic terror with state-of-the-art makeup and effects. Lots characters are killed in lots of ways, all very graphically and all shown on screen. There are flashbacks to deaths and violence from earlier films in the Saw series and extensive use of crime scene photographs showing dead bodies. There's also some strong language (including "f--k"), but the majority of the film involves sadistic brutality crafted by the film's villain as a series of "games" -- like a sequence in which characters trapped in a room with a bomb must volunteer to place their arms in a box with a saw so their blood will fill a jar; when filled, the jar will trigger the door that leads to safety. That's just one example; there are many, many more.
