I found this to be a generic killer shark movie that I have seen. The idea of someone modifying the shark gene to develop a new type of drug seems similar to Deep Blue Sea, and even the first part is some characters trapped in somewhat of an underwater facility. That part is somewhat suspenseful with the characters trying to survive against the shark and come up with some good plans for it. In the opening, the movie introduced a land shark that goes underground and can move easily on land. It's a pretty creative thing to have in a shark, and it shows how dangerous this creature is. There's even one scene that attacks a city, but it doesn't last long. Things get worse when the movie introduces a human villain who has a generic motive and wants to keep the shark alive. It's been done before, and here doesn't make it any better. The climax itself is ok, but nothing too big happened during it.
