PIRANHA

Roger Corman redefined the B Movie Creature Feature - well, B movies in general and helped create an entire generation of filmmakers.

His production of PIRANHA proves seminal b movie fare.  Weird creatures with a thirst for human flesh; hapless victims and boobies.  Ah, 70's boobies.

The plot is pretty common for the genre.  The government was trying to kill the Vietnamese by creating super Piranha.  The get into the river system and all aquatic hell (in Aquarena Springs no less) breaks loose.  The effect are cheesy, not really scary and there are plenty of Jaws references, including playing a video game named Jaws that is similar to a video game played IN Jaws.

Thankfully, the remake (which I love) is different enough that this one didn't pale in comparison.

At the end of the day, you're left with some bad, guilty pleasure fun.
