A car jock, his comedy sidekick, and a cute science geek have to work together to save the town from the destructive consequences of awakening an alien artifact of immense power. It may not be original, but it is a great idea for a story, and the first half hour or so works brilliantly. Unfortunately the logic and character development suddenly goes out the window at a certain point, becoming just an excuse for genre-jumping action sequences and special effects. Dennis Hopper shines whenever he is on screen: if this had been a movie about the science teacher, it would have been far more watchable. The other characters never really expand beyond their stereotypes.
The latter half of the story feels like it is assembled by taking a tour through a bunch of different sound stages on a Hollywood lot, and just hoping it'll all fit together somehow. Putting dinosaurs and laser guns and roman gladiators together may seem like the perfect recipe for excitement, but without a point to it, and without any sense of why or what is happening, there isn't much reason to care about any of it. There is no glue keeping all the assembled pieces together. It has a certain B-grade charm, but not enough to make it a classic.
