God Bless America review: 'I like it for its cri de coeur qualities, its spirited loathing of stupidity, bullshit, euphemism, cant and a crap, pseudo-patriotic culture based on humiliation and contempt for the audience. If you dug this film up in a time-capsule a century from now it might offer, maybe unwittingly, certain unpalatable truths about the suicidal Tailspin America of today that nobody else is noting'
