Chicago Reader review:
Superior 1975 Fassbinder film, with the wonderful Brigitte Mira (Ali: Fear Eats the Soul) as a hausfrau whose husband goes insane, killing his boss's son and throwing himself into the jaws of the assembly line. She becomes a symbol to the left wing and a freak to the right. No other director understands the strength of mediocre minds as does Fassbinder; when his films don't slip into derision, they can be ineffably moving, as this one is. The ending is impossible, but it is perfect (which may be why it's impossible).
Here (and above) is the opening.
