Another Cult Classic, the 1978 Piranha. It can be fun under the right circumstances, but the lessons from this film are based on its failure to follow them. Characters need to be interesting. The A, B, C stories need to line up. Dialogue has to serve a purpose, even on a rudimentary level. Piranha has none of this, so you can see firsthand what a movie that lacks all of the basics looks like. Still, it’s a good background film or a time burner. Surprising, with names like Joe Dante and Roger Corman, not everything can be a winner.

Piranha can be found on Tubi.
