I’ll be honest with you: sometimes the bad ones are much more fun to talk about than the good ones. Case in point: Mommie Dearest, the Joan Crawford “biopic” based on the tell-all book from her abused daughter who dished about what a horrible monster the woman was behind the scenes. The movie endures as a camp classic, notable mainly for the unhinged lead performance from Faye Dunaway that sank her Oscar-winning career overnight. I won’t say it’s good, but you will never forget it once it sears itself into your eyeballs. It opened today in 1981.
