Why all the hate for Margot?
I think that what many of these insightful deconstructions of the movie are missing is mention of the not uncommon adage that an insecure & sensitive person (like Margot) can wind up with an evasive selfish partner.
You can see straight off the bat at the flogging reenactment that she is too timid of a person to say no and stand by it (tendency to give in to pressure, be it direct or indirect) and how she legitimately tried to work things out with Lou in her own way (the only way she could see). I find his selfishness made clearer in his monologue where his focus is almost solely on himself (which is understandable in his shock of not preempting the result of his lack of intimacy) and in the end where he harbors an attitude that she *beep* up - not him. Relationships are two way streets and I think it would be safe to say that he did not reciprocate the level of intimacy she gave and required. I doubt there's need to mention Daniel's clues to selfish inclination what with his never ending attempt to sway her (causing so much grief for her - evidence that her well being is not his priority) and even blatantly self-interested remarks like "My birthstone is a 17 inch Macbook" (joke, yeah, but still evident of self-interested thought).
Maybe I'm just missing the whole commentary on how individuals in relationships are still individuals with their own sets of needs that may not be fulfilled by their partner and should rather try feeling complete in themselves? Goes hand-in-hand with insecurity - not feeling complete in oneself. I should mention that I tend to be an idealist with unrealistic expectations that someone could love somebody as much as themselves - but I'm ok with pushing the envelope because there would be no societal progress without. So I'm now thinking the the relationship demises must all boil-down to insecurity and inability to communicate what one desires (though, even then there can always be lack of reciprocity and a need to move on). I just don't understand where all this hate (not merely just lack of empathy) for Margot stems from, because it seems more like she is a victim of theme.
