Anyone who has seen Irreversible - what did you think about it?

I was so confused & nauseous from the beginning camera work (& sound that was meant to sicken the audience) that I decided to watch it "backwards" which made a lot more sense. I thought the fire extinguisher scene was worse than the rape scene which was way too long. I can't say I liked this movie. Especially since it was meant to be viewed the way it was filmed. I thought it was better in chronological order.
