Common Sense Note
Parents need to know that this is an extremely violent movie with repellent murders and killings that cross the border from self-defense into sadistic revenge. Customary guardian figures (husbands, mothers, fathers) are the first to be slaughtered. Not even director Wes Craven's later, teen-filled "Nightmare on Elm Street" or "Scream" movies strike a nerve like this.
The mother of the cannibal family is plainly stated to be a long-ago-abducted prostitute.
As gruesome as it gets (although some gore-fanciers have complained that the blood looks pretty fake). People and a pet dog are mercilessly slaughtered, a severed head is kept as a keepsake, and one character's Achille's tendon is graphically severed. Another is bitten by a rattlesnake. Rape, and strong suggestions of incest.
The film seems to make the point that beneath every person is the potential to be a monstrous savage.

The families drink alcohol.
