I just put it on my netflix. I'm purposefully giving myself low expectations so I can enjoy it. I confess I'd never heard of this film until a few days ago when I took my son diving and a couple people on the boat were raving about it. Someone mentioned that in real life they found a camera (waterproof housed) inside a mako shark and that was part of the movie's inspiration. Not a good day at the beach if you ask me.
Regardless, I should have known Open Water would have already been dissected here and that my ignorance is not everyone else's ignorance. I apologize. I promise to search from now on . . . no matter how ignorant I am.

Just watched Open Water. If you like diving and/or the ocean and you haven't already seen it I can't imagine you wouldn't enjoy it. DVD extras on shooting Indies was inspiring too.
I did notice the inexpensive cams at first but then the movie took off and I was completely in the moment. I can't believe they stormed Hollywood with an ME66, a beachtek, a VX2000 and a PD150. Thumbs up to Lionsgate for buying and promoting this film.
