Not historically accurate

Rating: 4/10 (25 December 2018)

No mention of Donovan being a spy himself. Half of the movie we listen lots of speeches about democracy values and justice as an explanation of Abel's great luck of staying alive. Meanwhile, if you compare the final sentences - 30 years for Abel and 10 for Powers - you'd be a bit confused. If you ever notice that of course, because Soviet court scene is shown quite brief, loud and weird. I haven't even heard what judge had said there first time I watched the scene.
They switched the way how Abel and Powers were treated as prisoners (Abel wrote that he was hit once, while Powers mentioned he stayed in a comfy cell and was treated well)
East Germany was shown as it was straight after Berlin surrender in 1945 (gloomy, with tanks, army, dirt, 100% bombed buildings + blue colour filter). It looked much better in 60s, just google it. Look at the pictures of Elvis visit for example. Soviets put loads of money there (as well as USA - to West Germany) to keep up with the race, it was their "shopfront" back then. And of course it could not be bloody snowing there in summer!
Abel was considered a hero after the exchange and officially was praised as a great spy. (They lied about it in the final afterstory credits)
I think if you take real events as a base for your movie, it's not fair to twist all the details like this. Even if you're dying to show countries and events stereotypically, please check the sources first, your movie only wins after that.
