"With an impressive cast list, and some visuals that bring up memories of Lucio Fulci, The Sentinel is a great classic that everyone should watch. There's something very dirty and disturbing about a lot of horror films from the 70s. Typically, they aren't as violent as horror movies can be now, but they frequently have a skin crawling effect that is currently lacking in the genre. The Sentinel is uncomfortable for most of its running time. From the very strange neighbours in Alison's new apartment building, to her terrible memories of the past, to an ending that you just won't expect, almost every moment will leave you with chills." - The film reel
