If you loved Phase IV, 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
Theysit in Horror / Science Fiction territory. If that's the register that drew you to Phase IV, 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.
