Query: Creepy as hell

This is a movie that starts off one kind of way with a bog standard cast and a bog standard "creepy ship" and then goes on to a very different place. Part of the accomplishment of this movie is that it's not based on shock value or on high production. It's based on psychology, and the lead actress carries off the emotional beats perfectly.
