“5 Headed Shark Attack” (**1/2 out of four) was a serviceable action thriller about the title monster who invades the calm and beautiful waters of Puerto Rico and a group of townsfolk (Chris Bruno, Nikki Howard, Lindsay Sawyer) who attempt to stop it but find this is one tough shark to destroy. As shark thrillers go, this is no “Jaws” but is one of the better of the lot over the past few years and gets better as it goes long leading to a suspenseful and entertaining climax. Superior visual effects by Steve Clarke as the 5-headed shark really does look terrifying!
