David Robert Mitchell’s It Follows is a clever psychological horror film that has a lot of thought and emotional depth buried under the genre trappings it so lovingly clings to. Essentially a commentary about the spread of sexually transmitted diseases, the narrative hinges on an unseen force coming to kill a group of teenagers who are “infected” by evil spirits, who target their victims based on sexual activity. These kids know that by having sex, they’ll be “infected,” and thus prone to the dangers of these supernatural entities, and yet they do what their hormones are telling them to do even though they know they shouldn’t. The film features some spectacular stedicam work, the direction is strong and smart, lead actress Maika Monroe (also effective in The Guest) is appealing and appropriately vulnerable, the sound design is sketchy all throughout, and the reliance on intelligent scares rather than cheap shock-tactics and excessive gore kept me engaged and interested. It’s also a film that abides by the golden cinematic rule of having a fantastic opening and closing scene. This is a really good “horror” movie for people who are looking for more than just a routine slasher flick.
