The Last House on the Left (1972) (Blu-ray)

Before horror fans Saw the current wave of shockers featuring fiercely Hostel villains, Wes Craven delivered this "important genre landmark" (Science Fiction Horror and Fantasy Film Review) that's thrilling, disturbing, action-packed and filled with unrelenting terror.

On their way to a rock concert, two teenagers (Sandra Cassel and Lucy Grantham) are kidnapped by a gang of escaped convicts. Although they put up the fight of their lives, the girls are drugged, tossed in a car trunk and driven into the woods by the savage, murderous gang... only to wake up to a horror they could not have imagined. Filled with shocks, twists, turns and action, this knuckle-whitening film "never lets us out from under almost unbearable dramatic tension." (Roger Ebert)
