This is a lot better than people seem to think. Its a good shark movie, but completely different then the more sedate Jaws and some of the scenes are actually quite scary. When i first watched this i must have been 9 years old and i WAS scared. It has humour, shocks, action what more could you possibly ask for? Who cares about a complicated plot, this is a popcorn blockbuster which you will enjoy for 1 1/2 hours. The simple plot works (scientist finds cure for Alzeimers in sharks brains, unfortunately sharks brains are too small for the drug to be widely produced so the scientists create genetically modified sharks that are bigger so therefore have bigger brains. Unfortunately (again) the sharks get smarter and etc. Also this gets 5.5 out of 10 and Deathwatch gets 5.6 out of 10, no way is that very poor excuse for a horror film is better then this shark infested tale
