For a stupid adventure/horror movie, this is fun. It is awkwardly structured, with a lengthy flashback inside a flashback, and an early scene, irrelevant to the plot, apparently thrown in just to pad the running time. The effects start out good but get progressively less convincing. However, so much is happening and nothing of it makes much sense that it doesn't really matter.
