The acting, the camera work,the visual work, the "twists" - other outcome then you thougt , the smart dialogues ,the confusion/nes, this is defenitly a thinkers movie, if you need everything layed out on a silver plate then this is nothing for you, I'm polish myself I don't know if the movie works the same or has the same impact if you reading subtitles tgey not always correct and the right understanding is kinda important in this, yet you can watch this movie five times and still find new stuff ,or understand some scenes in a different way, don't let the rating 6 ( age ) scare you there is swearing drinking etc overall this is a thinkers movie the subjects/s are adult stuff I would say Till late 16+ you will don't understand one thing in this movie , this. Movie mood/tone made me feel at home,I can highly recommend it, but some may say it's boring or don't fully work/confuses with only subtitles.
