What parents need to know
Parents need to know that this supernatural slasher about a serial killer who may have returned from the dead is full of slicing and dicing, with gallons of blood on display. There are also two instances in which adults hit teens. Language is quite strong, with many uses of "f--k" and "s--t." There are some sexual situations, including one involving teen pregnancy, but not much is shown onscreen. Most of the lead characters are 16, and the movie is being presented in 3-D (which, of course, makes everything that much more intense), so it's primed for teen consumption.
