Awesome beginning, awful ending

Rating: Null/10 (18 September 2012)

When I read the summary and saw the high rating, I thought that the film would be well worth seeing. The beginning was very good and made me want to see the rest of the film. However, as the plot was moving forward, it became somehow tedious, and the climax was the ending. The viewers are not given the opportunity to solve the number riddle and they only get a vague image of what the genius girl with the glasses in cooperation with the mentally ill man is doing and thinking. Much worse, I believe that there are mathematical inaccuracies. For example: It is stated that 30 has 3 factors. I know that 30 has 6 factors (1, 2, 5, 6, 15, 30), not taking the negative ones into consideration. In conclusion, it is about a film that it would have been way better if the numbers had had a different role.
