★☆☆☆☆ (as a film) / ★★★★★ (as a reason to drink with friends)

A secret genetic experiment in Venezuela goes awry (when do they ever go right?). Giant piranha, engineered to feed a starving world (a noble goal, executed poorly), escape into the Orinoco River. They grow. And grow. And grow some more. Soon, we are not dealing with a school of aggressive fish, but with that can leap out of the water to snatch helicopters out of the sky.

Cheap rum, a rubber fish toy for dramatic reenactments, and the mute button for the love scene.
