These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Crowning Music of Awesome: During 'President' Jähn's address to the nation, the national anthem of East Germany plays in the background, and then swells to a crescendo as the scene shifts to the Reunification celebrations.
And the short, but touching, piano piece at the beginning and end of the film.
Tear Jerker: Several moments, but the biggest is the ending, when Alex and the others hold a funeral for his mother and he comments on how he'll remember her and the country she was part of and died with. All while old footage of East Germany streets and his mother and sister at summer camp is shown.
