There is only a simple message. Not sure about you but I kind of saw earlier on how the title of villain is indistinguishably played on the various characters and their actions in the storyline. Howerver, that being said, it is a well executed movie.
Japanese crime dramas, from books, TV is unlike the Western "Who doneit", but more of the question of How. Greate example is the TV series Ten to Sen (Dots to Line) http://www.imdb.com/title/tt1067131/ Lately, they go even beyond that from the 'How' to the 'Why'.
And so is Villain. Not over the top, fairly realistic especially on the flash back on the key event. Not shocking, one can relate to most who are involved, even college grad.
A social commentary on various things that can happen to any developed society. This case is kind of sad and to some degree fatalistic real - except the ending.
Acting is fairly good. Maybe a little too much background to the main characters but then again they are the main characters. The alternating amongst the many side of the issue is natural, completed and balanced.
