Film noirs were one of the rare relatively high-profile Hollywood genres that could get away with a certain amount of moral ambiguity in the Hayes Code era of filmmaking, though even a number of film noirs had to concede to Hayes Code restrictions in the name of "protecting the sanctity of the family". Watching The Big Heat, it's a wonder this film made it past the Hayes Code censors, especially since The Big Heat takes a gigantic agitated sledgehammer to the institutions of law & order that the Hayes Code was so keen on upholding. The Big Heat is an utter nightmare for anyone devoted to what the Hayes Code stood for but it's a dream come true for everybody else just looking for some good cinema to enjoy.
