I mean it as no insult when I say that Indignation made me feel as if I was watching a picture produced in 1950s America. There are the costumes of course, with men wearing ties and tweed jackets all the time, and the girls with their long and colorful skirts. There is also the general mood of the settings, hinting at a time in which maybe things were a bit simpler than today, i.e: getting your pick of a campus job if you just fill out a form before they run out.
But what really convinced me of it was the acting. You know how characters in old timey movies sound different than today, as if they are aware there’s a camera on them and they have to recite their lines just like if they were on the theater? That’s what the acting in Indignation is like.
