A quite good and thrilling story with terrible over-dramatisation. Idealy a story starts with almost zero tension and slowly builds it up until the plot reaches its peak. This movie already starts with terribly much tension which is hard to understand at the beginning and later it cannot rise higher. Also, the mistery in the movie would have been an awesome twist, but there were so many clues in the first 15 minutes that it has just became boring to wait for the protagonist to catch up.
