Well, I rented this film as I thought it was going to be good.... Wrong again. This film is dreadful, story is a cliche, the concept weak and without any real content, with scenes that could have been taken from Jurassic Park, which did it better. Fortunately we live at a time with good CGI, had it been stop frame motion this would barely qualify as a B Movie from 1955. Adam Driver over acted by puffing and grunting at every opportunity (no real dialogue) and with every movement. Maybe he had asthma. Miss Greenblat played her part well but she didn't say much either. I paid a lot to rent this film as It's rather new, a waste of time and money.
