“Jurassic Galaxy” (*1/2 out of four) was a low-rent action thriller set in the desolate future in which a group of space explorers (Jonathan Nation, Eric Paul Erickson, Doug Burch, and others) crashland on an unknown planet and soon discover that the planet is inhabited by monstrous dinosaurs and that they’re on the menu. Yet another cheesy rip-off of “Jurassic Park” (in case anyone couldn’t guess from its clever title) which stomps this into the ground nearly 30 years later. Special effects aren’t bad considering the threadbare production budget but the dinosaurs easily outshine any of the characters, performances, and plot here.
