Lou Bloom is basically the symbol of 'White Supremacist'
He is the antagonist/protagonist of this movie who is a) white b) racist c) arrogant and prickly d) very self absorbed e ) AND a *beep* nut job!
I hate every thing he does in this movie. The ending of this movie is so typical : White male wins every time, it doesn't matter if he doesn't have a moral compass or a psycho.
