The crux of the movie is that something follows you and it can take any form it wants. The only way to stop it from following you is to have sex with someone else, then it will start following that person. Unfortunately, if it kills that person, then it will come back after you again. Unfortunately, only you can see it so if your friends try to help, you just look like a crazy person running from nothing. "It" takes a couple bullets in the film but keeps coming. "It" walks towards you so you can get away from it, but if it touches you, you're pretty much a goner as it has super strength.
I found the movie pretty creepy, but not super scary. The soundtrack is just a series of repeated creepy sounds like you'd hear walking through a haunted house; it became slightly comical as the movie progressed. If you like fantasy horror mysteries, you'll like this film, otherwise you'll probably want to steer clear.
