It's an emotionless pointless, plot-challenged mess of a movie, with fake looking sharks, and even faker looking people.
Some scientists are out in the middle of the ocean, trying to reproduce proteins in shark's brains.
These proteins are the cure for Alzheimer's, and one character even gives a half-assed speech about how she's driven by memories of her father's mental illness. Well, to harvest more protein, that scientist makes the shark's brains four times bigger than normal and now the shark's are super-smart and eat all the scientists. The only people they don't eat are chef LL Cool J and some other actor filling in for MacGyver, who must be too busy making celebrity appearances at shopping malls to play himself. I don't know where to begin in explaining the many ways a piece of shit can stink. This piece stinks of rotten beef, sour fruit, bile, lame-o plot, stupid, uninteresting characters, and fake computer graphics.
