"The fact is, the reverse chronology makes “Irreversible” a film that structurally argues against rape and violence, while ordinary chronology would lead us down a seductive narrative path toward a shocking, exploitative payoff. By placing the ugliness at the beginning, Gaspar Noe forces us to think seriously about the sexual violence involved. The movie does not end with rape as its climax and send us out of the theater as if something had been communicated. It starts with it, and asks us to sit there for another hour and process our thoughts. It is therefore moral - at a structural level."
