Martha is a typical Fassbinder film of social criticism, this time focused on marriage, how people marry for the wrong reasons, and how this ruins the lives of both husband, wife, and children.
In this movie, Martha, a 31-year-old virgin marries Helmut, a wealthy engineer. From dating to marriage, Helmut completely dominates Martha and makes her do things she doesn't want to do. He makes her ride rollercoasters with him which she fears, he makes her listen to his favorite music, makes her read a book about his profession which she finds boring. He even finally orders her not to leave their house, so that she can exist exclusively for him. He has very violant sex with her, which includes bites, bruises, even when she is heavily sun-burned. He both physically, mentally, and emotionally terrorizes her.
Why does Martha, at least for most of the movie, let Helmut do this to her? This is a result of a loveless marriage between her mother and father. Both were unhappily married, disliked one another, and often expressed that onto Martha, frequently putting her down. Her father makes fun of her all the time. Her mother calls her a disgusting 31-year-old virgin and blames the father's death on her. As a result of this, Martha needs someone like Helmut to dominate her and usually finds Helmuts sadistic behavior acceptable.
Even other people in the movie are heading in the direction of unhappy loveless marriages. Her boss at the library asks her associate to marry him after Martha turns him down. Martha's sister also gets married out of pressure.
At the end, the marriage between Martha and Helmut has tragic consequences. I think the message of the movie is a criticism of society and how many people get married for the wrong reasons and end up destroying their lives.
People anywhere in the world can relate to this movie and I think people should watch it before making the final decision on popping or answering the big question.
Note: The scene where he has violant sex with her on their honeymoon is quite disturbing.
