A very stylish horror film that, for once, doesn't rely on jump scares to get you going. The story is simple and that's why it works so well and the Demon that follows is just creepy in whatever form it appears as. The cast was great at how they portrayed their characters and the lead female protagonist really sells the fear factor of it all, the same could be said for the boy who.. Well, you know, gave it to her. The little bit of explanation you get is more than enough, though some people still want to have a complete explanation and bio on the Demon but IMO it's not really needed, not in this movie. I thoroughly enjoyed It Follows.
