Carpenter fans, seek this one out: a rare TV movie that serves as a dynamic B-side to Halloween. It doesn't have CinemaScope or a Carpenter score, but it's got his most Hawksian heroine, a fine jump scare, some nice nods to Hitchcock, a positively portrayed openly gay woman (on TV in 1978!), and a knowing way of contrasting a stalker thriller with everyday unwanted male attention. A hidden gem of his classic period.
A little corny, especially with Lauren Hutton's constant one-liners. But it's notable for the Carpenter elements. There's the mysterious outside evil attacking a person or group of people barricaded inside a building, and a lot of the visual elements appear have been practice for Halloween.
