Like others have said, this is a great remake and a classic in its own right. I saw bits and pieces of it on TV but didn't see the entire unedited version until college. It was interesting watching it with a dozen other college-age people because we were all pretty skeptical what appeal a (seemingly) corny 70's flick would have for us, but after watching the creepy build up and final, unforgettable scene there wasn't a single person there who didn't get the chills! It's hard to classify this one as it's a suspense/sci-fi/horror movie (in that order) but by the end of the movie you'll definitely feel an uneasy knot in your stomache greater than most horror movies could ever give. For those like me who were disappointed in the grossly overhyped THE BLAIR WITCH PROJECT, watch this instead for a great example of how genuine creepiness and horror can be conveyed without a lot of gore, although IOTBS has its fair share of special effects, all used very effectively.
