This movie defintely has no direction. Most of it makes not a lick of sense. If the creatures are carnevors what did they feed on all those millions of years locked away in the cave. If you are told in order to survive you must remain quite, why would you take your dog with you. I guess the dog knows how to use sign language. If you are using sign language why are you whispering. The creature are blind but follow sound. How hard is it for the government to lure them to an incinerator. I give up. I want my wasted time back.
