OK, there are some flaws in this movie but overall it can only be considered a modern classic. From the aged nursing home to the racial biggot sequence suspense reigns giving pure entertainment. Why this has not been transferred to DVD is beyond comprehension. As a cinema movie it is one i have never forgotten, the type of movie that remains embedded for twilight zone lovers. You can imagine my disappointment when continually searching for it on DVD. My fingers remain crossed !
