Not a bad story, but the low budget rears its ugly head at times to undermine the effectiveness of the movie. A lot of the plot is predictable, but the film moves quickly and takes some time to introduce characters so you at least have some involvement and know what's going on. An illustration of the low budget is when a motor boat is "destroyed," you only see this as a CGI image from a distance. (No boats were harmed during the filming of this movie.) I also love the "metal mask," that looks like a pie-tin mold.<br /><br />It's another big-sea-creature-on-the-loose story, but this one actually has an unusual motive for its vicious brutality (not simply hunger), a plot twist often absent in these made-for-TV flicks. The human characters are two teams of scientific artifacts treasure hunters (sort of an aquatic version of Raiders of the Lost Ark), and they're both after the same artifact. The bad guys all wear black so you know they're the bad guys; the baddest of the baddies (and the leader) always wears black suits, even though all the action is at a beach or on the water. Every line of dialog this guy has is a threat to somebody; they could have put a sign up saying "Generic Theat in Progress" whenever he shows up. The good guys wear other colors, even in their scuba gear so you know who's who during underwater fight scenes. The creature's inevitable attacks predictably interrupt these fights, and provide for other common monster movie clichés.<br /><br />Certainly not a landmark film, but OK for a watch if you like these sea monster movies, or if you have nothing better to do.
