This is a comic gorefest, by Alexandre Aja, as hundreds of teenagers gathering for a spring break, fall victim to the all conquering pirhanas. The central carnage sequence goes on and on as they fall from the collapsing rigging into the raging ocean.
SPOILER - it is both hilarious and horrific to see her too fall from the rescue rope as the fish devour her. It all starts with that JAWS survivor Richard Dreyfuss, but only for the first few minutes as the fish emerge into the sea ... various other characters like the sleazy porn merchant are finished off in amusing ways, flying cables slice nubile babes in two, a ponytail gets caught in a propellor, and that other girl swimming underwater with Kelly also has a grisly end; there is a neat payoff line as well. Does today's audience really go for this kind of stuff? Surely it is disturbing that there's an audience out there for films that mix graphic violence and explicit female nudity .... at least there are 350 outraged reviews of it at the International Movie Database (IMDB).
