I just can't give this movie a 5 star rating. I love its SYFY premise and story line, and its goofy special effects and big name actors in lead roles in this B movie. For a B movie, it is great! But, in a key sequence of the lead character going out to turn on the reserve oxygen for the science lab, scenes from Shark Attack 2 are used including the lead female diver from that movie (you'll see her flowing blonde hair and shapely body when it is supposed to be the male lead for Raging Sharks). Both divers in the scene for Raging Sharks were men and were wearing black diving suits when the scene began. All at once, one is wearing a blue suit and the other a dark red suit, and they are in the same mini-sub as in Shark Attack 2 complete with a speaker attached to the back and a couple of bricks of explosives. This is where the Shark Attack 2 dive scenes begin. They don't end until the male lead re-enters the science lab. Oh my! I bet someone plagiarized their way through film school.
