Query: Invincible Horror Classic

This is a classic, no questions asked. It's a classic because it stands the test of time in many ways. First, it is a very engaging and entertaining film. It'll never let your eyelids get heavy or let you fall asleep in boredom. Second, it is still one of the most disturbing and scary movies ever made. Since 1974 it has frightened its audiences because of its disturbing nature. It is definately one of the most unsettling movies I've ever seen and one of the scariest. This is a movie that needs to be seen to be believed. I can't just write to you to "see the movie, it's scary", you actually have to go and see it right now. Tobe Hooper and co. have created one of the greatest horror films to date, and this DVD does it justice. Over two discs you'll get commentaries, documentaries, trailers, stills, etc. It's a great special edition and I highly recommend it. Note: Avoid the sequels, remakes, and prequels.
