2,5 / The slavery horror - well documented, shocking sometimes. What I do not buy is the Hollywood schemes (lawyer's character, especially), and the Hollywood music (the elevating choir, as soundtrack for horror or key-scenes). (But I've really liked Stellan Skarsgård as a British marine officer, so cool, restrained, and effective, and also human).
To be honest I was a bit afraid of watching this because I assumed Spielberg would picture the horrors of slavery. He did not. Instead he masterfully gave profound hints how & which misery these people had to bear. It is Spielberg's unique craftmanship to transport the tortures right into your head without putting them on screen. I think this is the greatness of this movie. The rest is a solid court drama case.
A great historical event well used to portray the horror and unhuman conditions in which slavery took place throughout the Atlantic Ocean. Also an opportunity to outline an educational approach on the American politics concerning the subject, as well as the philosophical discussion underpinning it.
