Two people kicking against water, the sound of it and sharks. This is a film that attempts to do no more than tell the bloodcurdling story of a couple left in the middle of the sea. It isn't something that'll go down easy. Every cinematic element is used in the barest amounts with the exception of the camera. Not much has gone into developing the characters but that doesn't stop the characters from being real people. The sound of the water induces temporary aquaphobia. Open water is cinematic minimalism at its biting best. Its simplicity is what makes it so effective. It accomplishes what it intends to without attempting to foray beyond and entertains you without requiring your complete attention. Just let yourself into the world and you're in for a treat. Movies like Open Water are rare in the 21st century. The film rests on ideas, less on technology. This little gem of a natural horror based on real events is not to be missed.
