Scanning the posts, I see a lot of my faves have already been suggested so I’ll off “The Lives of Others.” After watching it, William F. Buckley turned to his friend and said, “I think that is the best movie I ever saw.” In German with subtitles. Not a very talky movie so you soon find yourself watching the movie and “hearing” the subtitles.
It’s funny how subtitles work. Within a few minutes your mind just sort of blends them in.
I second The Lives of Others.
