While going back and forth between posting and Wiki on the film's critical reception I lost my place and inadvertently saw:
...on the third day. ...During sex she either has an orgasm or is disgusted by what she is doing, then dresses herself and stabs the man to death with a pair of scissors. She then sits quietly at her dining room table.
Either/or, huh? Either has an O or is disgusted and stabs the motherfucker to death as consequence? Can't say that's ever happened to me! Thank you, Wikipedia, you just saved me one hour and fifty minutes of viewing. Greatest film of all time, huh?
