Buy this in blue ray just for the underwater scenes. You will do David Duchovney proud.
Also other people don't see eye to eye with me, this movie started the new Genre of Treasure Hunting movies ie. Fools Gold, etc. The story does seem to drag a bit about 3/4 through, but it's a good movie, entertaining, and features really good looking people in a tropical setting. Great to watch in hiDef on a 50" screen.
