AFAIC, that is one of the most impressive scenes in the whole trilogy. Look at Sonny's face, he got something really savage in his look. And all the people gathering to watch, the kids, the rubbish. I like that scene, as violent as it is. Don't care much about the minutia.
I don't want realism. I want magic! Yes, yes, magic. I try to give that to people. I do misrepresent things. I don't tell the truth. I tell what ought to be truth (Blanche/A streetcar named desire)
