You know those movies they make on a single thought and the rest is just background noise? This one of those. The plot is simple: people on a ocean research station are being chased by the super-intelligent sharks they were studying. It may sound somewhat deep, but it’s not. It’s jaws with a twist, the station being mostly underwater allows us to see shark attacks in places we normally would not.
Samuel L. Jackson and Thomas Jane give the best performances, but the former is only in the movie for the first half.
If you can handle sharks eating people, then there’s nothing in this film you can’t handle.
Super-smart sharks eat people. I don’t know enough about shark brain research to know if we can make sharks smarter by experimenting on them, but the rest of the movie is pretty ridiculous regardless.
