why i think the torture scene works
a lot of people feel the torture scene went too far, they say it should have stopped after Chang stabbed the guy in the legs, at this point while watching the film, i was actually thinking "is that it? i was expecting a lot more from the Refn, maybe his talent for violence is waining a little, given how extreme he usually is". then he stabbed the guy in the eyes and ear then it cuts away, that's what i've heard people say went too far but when that happened i thought to myself "ah, that's more like it".
if the torture scene made you feel uncomfortable or distressed or disturbed, then honestly it sounds like the scene did its job perfectly, criticising a torture scene for making you uncomfortable is like criticising a dinner scene for making you hungry.
but that's just my thoughts on the whole thing.
