If I squint, I can see the influence of Douglas Sirk on this Rainer Werner Fassbinder soaper about fruitseller Hans Hirschmüller. He's cast as a failure, because he doesn't live up to the middle-class aspirations of his family. He runs away and joins the Foreign Legion. He returns and joins the police, but is kicked out for consorting with a prostitute. His one true love can't marry him because of his work, although she meets him for assignations. In between, he has a shrewish wife in Irm Hermann, in-laws who despise him, a heart attack, and his gradual erasure from his own life to contend with.
However, while Sirk's most famous work in the 1950s tinges his disapproval of the post-war middle class with sympathy and wonderment at peoples' refusal to admit what they want to to be happy, Fassbinder seems angry and contemptuous of his subjects. Hirschmüller is too passive, Miss Miss Hermann plays the victim card too aggressively, his family arrant, mealy-mouthed snobs, and so forth. There's no one to root for in this. There's nothing tragic about his inevitable destruction, only a sadistic, scolding examination of all that Fassbinder finds wrong with mainstream society.
