Within 10-15 mins of watching was able to predict the rest of the story. So was not that interesting. Plus several scenes made the movie look very amateur (breaking into the house to release the girl), not noticing missing friend on the car ride, etc., Most importantly they didn't give strong character and motivation behind the actions of 'Cornelia'. I recall at least couple of movies made before based on similar theme.
net-net, so, simple time pass. nothing extraordinary.
