This one is about sharks, not dinosaurs. Any idiot could see the difference. Aquatica is in the middle of the ocean, but it's located on an old WWII submarine refueling station, not an island. And yes, the lab is reduced to a skeleton crew for the weekend, but that's normal operating procedure and has nothing to do with the fact that a big storm is heading right for Aquatica. And now the sharks are turning on their human masters, escaping into the wild to chew up pretty, golden, unsuspecting white teenagers.
Damage control is in order.
There's no point in trying to remember any of their names. I mean, people left on the underwater lab to know that only the prettiest and highest-billed among them will survive the next 90 minutes. Legs will flail underwater. Big red buttons will get pressed in slow motion. Dialogue will be stilted and overly expository, unless it's a quip.
