Totally overblown IMO. Here's a few fun facts I pulled off a shark website:
You are 1,000 times more likely to drown in the sea than you are to be bitten by a shark.
About 100 people in the world are bitten by sharks each year. Of these, five to ten die mainly from blood loss.
The chance of being killed by a shark is one in 300 million. The chance of being killed by airplane parts falling from the sky is one in 10 million.
More than 70 percent of victims of Great White Shark Attacks survive because the shark realizes it has made a mistake and doesn’t finish off the prey.
A shark attack on a human usually occurs in less than 6 feet 6 inches of calm water, and within a relatively short distance from shore.

Pigs kill more people every year than sharks do.
