In short …

… 'Truth': A Terrible, Terrible Movie About Journalism - The Atlantic.

…  The movie loudly, hectoringly stresses the importance of always “asking questions”—my notes include, among others, the lines “Questions help us get to the truth,” “You stop asking questions, that’s when the American people lose,” and “You’re supposed to question everything, that’s your job”—and yet the very quality it celebrates in its protagonist is that she never questions whether or not her reporting might have been wrong. This is a film in which acknowledging error is treated as some terrible surrender and betrayal of trust; in actual journalism, it’s considered a moral obligation—one that, sadly, most people in the field have had some experience with, in one capacity or another.
