BackFire
Blood. It's nature's lube
Irreversible is a masterwork.
The fire extinguisher scene is one of the most affecting scenes of gore I have ever seen in any movie, while not overly bloody, it feels truly genuine which makes it very stomach churning.
And of course the rape scene is just awful, one of the most powerful scenes in existence.
Best thing about the movie though is that it's cerebral. The parts after the violence become among the most affecting in the film because they're cast in the shadow of the inevitable tragedy that we've seen but that the characters haven't. So things that would normally be seen as touching or moving are now tragic and heart breaking. Great film, can't wait for his new one, Enter the Void.
