How to make a bad movie. First call it "Cave."

Wretched garbage. Had some potential in the beginning, but failed to deliver much of anything in the end.

This movie was aweful. I was really into it in the beginning. I thought they had a good story going. Go into the cave, find a new ecosystem with new creatures that have evolved because of lack of sunlight. I love biology and was interested to see where they were going with it... then it took a nosedive. It turned out to be one of the most ridiculous movies I've encountered. It reminded me of one of those cheap movies on "scifi"
