This movie just plain sucked, despite having Lena Heady (pre-Sarah Connor and pre-300).

Send a bunch of seasoned spelunkers and biologists into a quasi-mystical Romanian cave system, and the best they could come up with to hunt them was the deformed love child of the Alien and the things from Pitch Black?

This film had a budget of $30 million–I wonder how many cups of coffee a day that could have bought in order to save children?
