This film is one of those turkeys that is enjoyable because you can predict things and watch the worthy efforts of some good actors to make the best of it. It looks like very low budget stuff -- one of the funniest bits is the first earth tremor, with actor reactions and camera shake working overtime. We see the hero and a friend perched on the edge of a cliff in their SUV, but only in close shot, because it cost too much to build a post-earthquake set. There is also a wearisome personal subplot that makes Invasion seem fast-moving. I am not rating it because these turkeys with redeeming features are so hard to rate if like me you sympathise with the production problems on low budget.
