Talk about guilt and pleasure, like peanut butter and jelly. There have been three Shark Attack movies, I've seen them, but I only own the third one. Where do I begin to explain why? Who cares. Its all about the characters. When the two leads join together to chase after the shark to save potential victims. The female, Cat (a shark researcher) screams ,"Oh my God," with her hand cupped towards her mouth everytime there is a close call with the shark or an actual attack. It looks like she's laughing. Its funny. Later on after the shark has attacked their boat the shark is after Cat, so the guy, Ben (the resort security diver) tries to save her by attacking the shark, so the shark turns on him. Ben then starts screaming like a girl and then he needs to be rescued by her. Its classic. And if that did nothing for you, maybe what he mutters to her while they discuss their evening plans will be enough for you to rewind over and over again. You heard right. And it was improv.
