A good horror film builds layers of dread slowly and meticulously, generating a nearly unbearable sense of fearful anticipation in the viewer before finally resolving it. It Follows performs the first step beautifully. Its voyeuristic long shots, paranoid circular pans, and corner-of-the-eye glimpses of the monster create such terror and tension that many claim to habitually glance over their shoulder after watching the movie. It’s a palpable, visceral anxiety that few modern horror pieces manage to achieve.
On the other hand, a good horror film also has satisfying moments when all of the tension is broken. This is where It Follows falls flat. The film’s monster is terrifying because it’s elemental and mysterious, a being that the viewer and the characters can’t quite fathom. The terror that it creates so effectively is cheapened a bit when it builds to fight scenes that pit a group of friends against an invisible, Herculean, shape-shifting brute. In order for a resolution to be satisfying, it must be compatible with the means used to build fear in the first place. Otherwise it can come off as a shoehorned action sequence intended to universalize the film’s appeal, which is never a good thing.
Don’t let me scare you off from this piece, though. It’s worth a look solely for its elegant generation of anxiety and stripped-down horror. But be wary of the action, as it dulls the film’s edge.
