This movie is so awful people should watch it to see how awful one can get. If you put aside the terrible acting, stupid dialog, really really bad effects, if you put aside that people who wrote the story didn't give any thought about how mines look, how caving is done, what bugs look like and how they act, if you put aside that characters in the movie always do the opposite what you would do you are left with a story that has more holes then all the swiss cheese in this universe. The outline of the story is not that terrible really, but what they have done with it is something completely else. In the beginning I said people should watch it to see how awful a sci-fi movie could get. But keep in mind this is more like a parody than a real sci-fi.
