I thought it would tell such a story: one has to cross the line to the darker side in order to have the power to shed light again, but he or she will lose the true self in the process. Nevertheless, it turned out that the film was still promoting justice.
passion past, and maybe the girl is exactly a smart guy who can past the exam in such a short time. that is not ordinary in our life. but the whole movie seems positively and pretty good.
