This movie single handily ruined my babysitting career! It didn't matter that I usually babysat in single floor homes, or that they only had one phone / phone number attached to the house. The whole idea of that movied scared the crap out of me! In '79, I was 10 years old, (telling my age), and roughly the time I began to babysit.... Wrong movie to see at that time!! LOL! But I can't WAIT to see it again! :) By todays standards, people might say it's not scary or that it's just plain silly... Give it a chance! It's one of the best supsense/thriller's I know of!
