Given this is Holocaust Remembrance Day, I highly recommend The Boy in the Striped Pajamas, Playing For Time, and The Pianist, all on Netflix. The latter shows what prolonged isolation can do to you.
On Amazon, Spring 1941 with Meryl Streep is still good, and Conspiracy about the Wannsee conference is excellent.
Unfortunately, Europa, Europa is now unavailable, which I think in its quiet way was excellent.
If you can stomach it again, Schindler's List is on STARZ. I almost had a breakdown watching it, so never again.
Oh, if you want to watch one time when they fought back and some actually made it to freedom, watch Sobibor.
No good "fictional" version of the Uprising at the Warsaw Ghetto has ever been done in my opinion. Although, in that case they virtually all died and knew they would die, it's an extraordinary story.
