If you loved Twilight Zone: The Movie, try Piranha
A bridge between a film you've already seen and one most people haven't. Here's what they share, and what the second one does that the first one doesn't.
What they share
Both films are directed by Joe Dante, and they both carry the dread, late night mood tags, and they sit in Horror / Science Fiction territory. If that's the register that drew you to Twilight Zone: The Movie, the second film will land in a comparable space — through a different lens.

What Piranha is
Lost River Lake. Summer. A beer can floating. An amnesiac woman and a down-on-his-luck drunk search for missing teens, only to uncover a military experiment gone wrong. The feeding begins. Dante's B-movie is better than it has any right to be.
