I feel bad for ol' Bank who basically had done a complete 180 by the end of the movie. Also Grace was possibly the most selfish person on the planet. Also, what's the deal with the school fee of 200,000 Bahts?
Overall I'd give the movie either a 6/10 or a 7/10. It was decent, but only really liked the first cheating method. The second was convoluted, and went on way too long in my opinion.
