I'm shocked that the discussion didn't touch on the final line of the film which is a stunner that haunted me for quite a while after I watched it. (I'm referring to that brief exchange between the Mademoiselle and Etienne, through a closed door)
I think Adam's arguments for the film were extremely compelling and I went from wanting to vote "no" to a pretty confident "yes." This is a challenging and upsetting film and I almost stopped watching about 2/3 through, but I'm glad I stuck with it because I could tell it was transcending "torture porn" and doing something powerful and subversive. I don't think I've ever been so devastated by a film but I think it makes an important point.
Pretty sure I'll never watch it again, though.
