This could have been a great film. But your critique is spot on. It was bearable for the most part, notwithstanding the broader ahistorical flaws. But the whitewashing of Churchill, showing him to be friendly to a black man was more than I could take.

The guy spent his life committing heinous racist and reactionary crimes. His was anti-Semitic and he spoke of black people as inferior, by which he included more or less anyone south of Calais and east of the alps. He purposely decided to starve/abandon to the enemy three million people in India. Prior to all this, he was known for calling the army on striking workers and shooting them in the street. He was no anti-fascist, I’ll put it that way.
