Reactions

The Best Years of Our Lives (1946) is good, but long - almost three hours. The first hour, all on its own, is about three men returning to their hometown of Boone City, then finding each other again after each is differently disappointed by their reception.  While the film is not a documentary, it can feel like a historical document, showing how people perceived the world right after World War II had ended.  Some of the observations seem shockingly prescient - one person comments about the likelihood of a postwar recession. (There were two within five years of the end of the war, one before the movie was released, one after.) Other observations of note from that first hour:

• Warplanes on the ground, built too late to take on the Axis powers, "from the factory to the scrap heap."
• Myrna Loy's husband looks like her previous co-star William Powell.
• Two references to the possibility of global thermonuclear war, and this three years before the Soviets succeeded in their nuclear program.
• A teenage son being brought up as a good Adaptive, talking about the Japanese as fellow humans rather than enemies, and wondering about the dangers of the new atomic world. (And also not too keen on accepting war trophies from his father.)
• It was clear that the Captain Derry was going to have Post Traumatic Stress Disorder, almost as soon as he was seen sleeping.

There's a Harry Potter Fan Fiction that seems like it might have been inspired by this. Amends, or Truth and Reconciliation, considers what would really have happened to a group of teenagers in a war, fighting and tortured and in some cases committing war crimes in response to the actions of a terrible foe. Short answer: Everyone has PTSD, presenting in different ways. Harry is withdrawn, Ron becomes aggressive, Ginny turns into a mean drunk, Hermione exhibits accidental magic (sometimes in her sleep) and Draco has...performance issues. (All the Weasleys take what Lucius Malfoy did to 11-year-old Ginny very personally, as well.)  There's also Hermione's debt to Gringott's, her work at the ministry to pay it off, Neville working with war orphans at Hogwarts...The post-war isn't ever what's expected. 

(Fair warning 1: The fanfic has some sexual content. Fair warning 2: It is not complete and may not ever be - it has not been updated in some years.)
