Fantastically entertaining creature feature and disaster film with plenty of horror tropes thrown in for good measure. This is one of those films made simply to sit back and enjoy for the sheer fun of it all and who doesn't love a good shark film? Action director Renny Harlin throws all his usual flair into this, it's all brilliantly done, tense, exciting and wonderfully gory at times. A deep sea laboratory led by scientist Susan (Saffron Burrows) is trying to find a cure for Alzheimers disease from a fluid found in the brains of sharks. With her team she has genetically engineered three sharks to produce sufficient quantities of the precious fluid but a side effect is the sharks have grown larger and more intelligent. When a storm hits the lab everything goes awry. The cast are all having great fun including Thomas Jane as the 'shark wrangler', Stellan Skarsgård, LL Cool J and Samuel L. Jackson. There's some superb surprises to be had along the way. The obvious influences of Alien (1979) and The Abyss (1989) are there for all to see. A film you don't have to think beyond what you see it's just for a great time.
