The Thing is about a monster from space that infects a group of guys working on some kind of research base up in the Arctic Circle somewhere. And The Thing is, how can you explain it? Go on, you try. It's a shape shifter. So it takes on the form of the person that is inhabiting or absorbs their essence and can shape shift to form. But when it changes from one form to the other, its appearance is like really, really, really scary. And like, like hallucinogenic or something, it's so frightening. There's lots of tentacles and things moving and very, very weird and scary gore and monsters and stuff.
