One of the better rip-offs that were made after the success of "Jaws". The idea of actually many hungry killer fishes eating people slowly away is actually even more gruesome than "Jaws" as well if I start to think about it. Love the cheap effects that were meant to "scare" people. Great supporting help from beloved cult actors and actresses, but it is not as funny as it could have been.
Still crap, after all these years... and yet, still a million times better than the recently released dreck that is Piranha 3DD (not to be confused with Piranha 3D by Alexandre Aja, best of the bunch).
