We watched this film in school the other day. I thought that it would have just been some half-hour National Geographic special on the ocean, but it was actually a real movie. They showed us creatures at the bottom of the ocean, and more. The cinematography was excellent, and the music score was also well-done. It always fit with what was going on. It wasn't just some footage from Jaws 4 and an Australian-voiced cartoon character making shark jokes. It was a very well done film, and it was narrated by Pierce Brosnan of James Bond fame. I suggest renting it or something. Hope this review was helpful and all. I give Deep Blue an 8/10.
