"All My Sons" is one of those disappointing films that goes far enough in a certain direction to become somewhat interesting but doesn't really follow these ideas to any kind of meaningful or even dramatically satisfying conclusion. To how much of an extent that was the fault of the original work by Miller and how much was due to the changes by the screenwriters it's impossible for me personally to judge because I'm not familiar with the material. But regardless of the reason, in my opinion it doesn't add up to a particularly good film.<br /><br />Chris Keller (Burt Lancaster) is the somewhat disillusioned son of an industrialist, Joe Keller (Edward G. Robinson) who happens to be in love with the daughter of his father's former business partner (Howard Duff), Ann Deever (Louisa Horton). What could have been a rosy small town setup however has been sent off the tracks by a criminal investigation into the war-time practices of the company, which was accused of passing off defective parts which ended up killing American pilots  Ann's father has been sent to prison for a crime that it becomes increasingly obvious was probably just as much Edward G's character's fault.<br /><br />The great weakness of this film is that it's completely obvious that his character is the guilty one. Otherwise there would be no story at all. And a moral dilemma should really have more weight than this one. Should Keller have rejected the defective parts, even if it meant shutting down his plant? Obviously he should have rejected them, so there's really no dilemma. The film tries to convince us that his plant would have been forced out of business if he had rejected them, and yet at the same time shows us that his business was booming during the war. This makes the economic element of the dilemma unconvincing. And even if we did believe that he had to choose between rejecting the parts and closing his plant, his speech about how hard he's struggled to create this legacy for his children hardly inspires me to empathy with his "plight".<br /><br />As if to quash any last possibility of compelling drama, the film's eventual conclusion focuses on a letter from Chris' brother, who died in the war. His letter, which the film implies should be like an earthquake of drama shaking this family, is instead predictable and its tragic consequences are also predictable.
