There's been a lot of warnings in the media about genetically modified crops of late, but at least they don't devour people whole. The GM-sharks in this film certainly do, and in chompingly graphic detail.
The plot is fairly straightforward; Saffron Burrows and her team of scientists have only 24 hours to persuade Samuel L Jackson, her main backer, that their work on shark's brains will help all mankind cure Alzheimer's disease.
Sam and Saffy take a trip to her oceanic research base where everything goes swimmingly, until the sharks suddenly get clever and start working together to plot the downfall of all aboard the research base.
The film quickly mutates into a cross between Jaws, Titanic and Jurassic Park, and sharks start pursuing the intrepid team, with the intention of picking them off one by one. The film's a bit more gripping than Titanic (and certainly not as long), and the sharks are less crap than in Jaws.
There are a few surprises along the way, including a creditable performance from 80s hip-hop star LL Cool J, as the base's cook (although why no-one was worried about his parrot putting droppings in everyone's tea is still a mystery to me). The biggest surprise of all, which will have you guessing right up to the end, is who ends up as shark nibbles and who ends up escaping. A good action movie, but don't expect anything deep from 'Deep Blue Sea'
