It reminded me of a 'Hallmark Classic' then again most of....

Rating: 5/10 (13 March 2016)

...Spielberg's films do.
Even allowing for the time (1957/62) difference (2014), the scenes reminded me of a 'stage set' - faux walls, sky etc.. In addition the award to Rylance wasn't warranted. His script was nearly a monotone and always let Spielberg make a bolshevik/red 'human'.
The historic accuracy re. the second 'captive' 'Pryor', was false - another 'trick' by Spielberg to 'add' some human/family hook.
A far better script would have added after successfully negotiating the exchange for Francis Gary Powers, Donovan's negotiated the freedom of initially 1,103 but expanded to 9,703 Cuban anti-Castro men women and children.
With Spielberg, as with all Hollywood leftists, there is always the kid glove treatment of the horror of the reds, even allowing for the callous machine gunning of the fleeing East Germans over the wall. In Schindler's List, Spielberg made sure he got his anti-gun message in the final scene when the Jews are surrounded by the German SS guards and tell them (the Germans) to go. In the movie no one has firearms in reality the Jews did and had them pointed at the Germans.
