Open Water (2004)

Truly frightening at times but doesn't work as a whole for several reasons.
1) The actors were not believable.
2) The characters were not likable.
3) The music with vocals was extremely distracting.
4) It suffers from "The Perfect Storm" syndrome: I hate when "based on actual events" movies create a complete fiction when there's no way of knowing what actually happened. It insults my intelligence, frankly. It's arrogant for them to pass this off as "true" when, at best, it's "inspired by" or "suggested by" true events.
