This is what an actual strangling looks on camera?

It looks so incredibly fake. My point being is that, realism, popularized by hacks like Nolan, Fincher, Tarantino, is massively overrated and quite simply not needed. There is no need to jeopardize a person's life, for a movie, and specially if these are the shitty results. Richard Burton choking Elizabeth Taylor in Who's Afraid Of Virginia Woolf? is endlessly more believable and realistic than the piece of shit choking above and I assure you there was no real choking in that film, although Mike Nichols was sadist behind the camera, just like this fucker too, so sad.
I have to say I'm very disappointed in Hollywood and America as a whole. I come from a third world country and let me tell you, these are third world country practices. It pains me to see people being abused and exploited in such a way in the US, it's pathetic.
