My favorite Russian movie is “The Fall of Berlin”

I mean it’s slavish devotion to Stalin is so over the top, especially the ending when they show Stalin arriving in Berlin. (Although no such trip took place, Stalin only went to Potsdam, but it was much more low key)
But “Brest Fortress” really is one of the best war movies I’ve ever seen.
The only thing I like the arrival to Berlin is for the make up for actors playing Stalin, Churchill and FDR. Oscar-worthy. Other than that it was a crappy piece of propaganda.
