Dark Breed

Reptilians! The story is shallow, but what's there is fun: astronauts, aliens, government conspiracies. The rest is absolutely jam packed with action. There are several car chases, countless gunfights, innumerable explosions, and a possibly record setting amount of shattered glass. The stunt coordinator gets first billing in the end credits, and fair enough. Would've been nice to get deeper into the conspiracy angle, but if you don't mind shutting your brain off it's a good ride.
