The Marriage of Maria Braun (MMB) is about a German girl (Maria) getting married to a German soldier (Herman Braun) just at the ending of the war. After being married for half a day and a night, Herman is send to the front again. To make ends meet, Maria starts working at a bar for mainly American soldiers and get to know a black soldier. She got word that Herman died at the front, and things develop between her and the American soldier. Herman walks in on them, in bed, and after a confrontation between him and the American, Maria killed the American. Herman admits to the murder, ends up in jail and Maria vows to wait for him. The country is in shambles; one sees people leaving everything that they are busy with for a cigarette. There are food shortages. It is in short, a time of survival of the fittest.
Basically this film projects Maria's attitudes - those attitudes she permits herself under the mentioned circumstances, as a metaphor for Germany's loss of soul after they lost the war, and how it proceeds to rebuild itself. For example, Maria has the following conversation with a peddler (played by Fassbinder himself); the peddler tries to sell her an excellent copy of Kleist and she remarks that "Kleist burns out to quickly, it does not provide enough heat for the cold". The peddler answers "That's another way to look at it. Right now, it's probably the correct way".
Maria meets a French/German business man, Karl Oswald after she bargains her way into the first class train compartment. She decides to get involve with Karl, "You're not having an affair with me; I'm having an affair with you". She also takes responsibility in the company, and after a while has the complete trust of the firm. When Karl says "I suppose we'll just have to wait for a miracle" she replies "I prefer making miracles  then wait for them". In her own words, she has become the "Mata Hari of the economic miracle".
In a lot of Fassbinder's films he tried to expose the psychological processes which lie behind social mechanisms (see Freud); in other words, he liked pointing his camera at the bullsh*t, the false social mechanisms, the pretending. The direct approach Maria takes in this film is successful to convey this ideology. For example, she phones Karl and when he picks up the phone her request is straight to the point "I need someone to sleep with". As Fassbinder said "the emotions people felt did not exist at all and were only a kind of sentimentality which we thought we needed to be properly functioning members of society". He also remarked that his films are anti emotional.
I particularly liked the scene when Karl and Maria meet in the Munich restaurant (apparently, frequently visited by Hitler himself). Maria appears in control and Karl a bit on the down side, as if Maria's 'brutal honesty' wears him out, as if he is not completely up to the situation anymore. Karl says "I have to tell myself over and over that I love life". Maria replies "That's life isn't it. As if we signed a contract to enjoy life. And then we go out to eat and talk about food". I guess this is also about Fassbinder attitudes on relationships, to never submit completely to anyone. And why would you, if the central matter of most of his films is about "What love becomes in this society  a commodity, an instrument of power, a weapon."
It was remarked that it is typical Fassbinder to have the scenes with Maria and Betti walking in expensive dresses in the ruins after the war - with these clothing essentially the wrong period. What I think he wanted to portray here were those attitudes, when you feel bad, that "you can always put on your make up and face the day looking great". But, Fassbinder was not interested in perfection. Any mistakes made in a film could just be corrected in the next project. Since he completed films (approximately 4 a year) the way other people rolled cigarettes, it is not peculiar that this film has some very bad scenes. Peter Marthesheimer, who wrote most of the script, mentioned that Fassbinder likely dreamed up the whole scene with Maria and the American in the park, overnight.
Hanna Schygulla is brilliant as Maria. Mostly, she just stares bluntly into the camera. In Maria's own words "It is a bad time for emotions. But, I like it like that".
There are different opinions about the end. After Karl died of a hart attack, Herman finally shows up. (Herman left for Australia after he got out of prison, to "become human again".) After the testament is delivered (made out to her and Herman in half), Maria forgets to close the gas on the stove when she lights her cigarette, and blow her and Herman up. For me it is obvious that she just did that by accident. At the same time, she must have been rattled when her dreams finally seem about to come true. She must have felt as if she was not herself anymore. She felt as if she had outlived herself.

I am usually disappointed by network movies. Even flix that attract big name actors are usually ruined by the TV people. However, this one is the worst of the worst. The screenplay is weak and the acting, especially that of Tracey Pollan is abominable. I've trudged off to see my kids'high school plays and been treated to better acting. Pollan acts as if she is reading the script as she speaks. When she tries to express fear, anger or grief, it's extremely hollow. Because of the overall quality of the production I found it difficult to take it seriously. If you decide to brave this one just be prepared for a big disappointment. Scary things won't scare you, sad things won't make you sad, romance won't make you feel warm and fuzzy and you will likely be as anxious as I was to see the end arrive. "First to die" says a lot about this movie.
