Even though this looks a little silly now, folks were terrified and unnerved by this monster in the 1950s. Folks everywhere were terrified of heading out onto a boat! Ricou Browning reprised his role as The Gill-Man multiple times.
The Monsters in It Follows
It Follows is a different take on a psychological thriller. An unknown entity, invisible to everyone but the person it's following, is on a slow mission to kill its prey. The entity takes on different forms of humans. Sometimes, it can be someone you know. A lot of these entities were always off-looking, whether they were completely naked or horribly banged up and bruised.
