Piranha is bad 70s creature feature gold! It's so bad it's great and a fun ride as long as you expect a total cheesefest.
Piranha is cheesy 70s/80s creature films at their very best! It has everything - evil military generals, obligatory lake celebrations, scientific experimentation gone wrong, horrible dialogue, low-budget effects, and more. It's clear as you watch the film that Piranha was heavily influenced by Jaws, with the city ignoring the warnings of the dangerous underwater creature, the very similar movie poster, and much more. Steven Spielberg has even named it his favorite Jaws rip-off movie. This low-budget gem was a zeitgeist of creature horror cinema of the decade that didn't allow bad effects, poor acting, or no money to stop them from making their movies. The remakes in the 2000's just used this movie as an excuse to show a lot of nudity, and while there is a little nudity in Piranha (1978), it is much briefer than its predecessors. Pirahna (1978) focuses on letting the army of hungry fish gnaw on its helpless victims. This goofy little creature flick launched the career of director Joe Dante, who later collaborated with Steven Spielberg himself to make Gremlins - a real creature masterpiece! Piranha is no Gremlins, but it sure is a fun start to Dante's creepy creature-filled career.
