Hah. Bless.
Categorically, the worst film I’ve ever watched, by a country mile, was Open Water.
It was just so p155 poor on so many levels. The two main characters are completely bland; I’d say they were immediately dislikeable, but they weren’t that good. The camera work makes The Blurred Witch Project look professional. The plot is absolutely non-existent (two people go on holiday, get lost in the ocean, argue a bit, get nibbled at by sharks, the end). There is *nothing* in the way of plot twists, character development, anything at all to hold your interest unless you have a “two people floating around a bit” fetish. The most exciting bit of the entire film was one of them having a wee.
