It was a great movie showing solid greed of humans. Despite most of the Iranian social movies that follow a quite scenario, the "Butterfly stroke" has a scenario focusing of the new aspects of Iranian scociety. The film is focusing on the life of Iranian hood-lums and gangesters which I belive it is a novel idea in Iranian movies. Similarly, the dialogues are full of slangs. I believe the scenario at could be better, if in the final episode, Hashem who was in the prison was informed about the identity of the the man who ordered taking photos and video clips from her wife.
