What an incredible, incredible movie.
I'll need some time to properly digest it and I think it deserves at least a 2nd vision to notice other details, words, glances and gestures because so much is said without using spoken words.

It is a stunning journey through grief and growth, with a very peculiar (for us Westerners at least, I feel) pace: slow, for sure, but also contemplative. It felt like being able to embark on the journey with the characters, thanks to their willingness to listen; I'm not sure exactly how to describe it, but in a U.S. movie I would have expected rage, emotions bursting, maybe crying - which for me if not done properly, disrupt the rhythm of the tale and sort of wake you up from your identifying with the people on screen. Here I felt characters internalized, reflected on the moments that shaked their core, allowing us to reflect with them.
Furthermore, the fact that little actually happens, allows to take the proper time to hear the characters, let them explain themselves slowly and not always with words - which I found a superb way to depict a human in a multifaceted way.

There are at least a couple of scenes I found remarkable: the dinner, the 3 people journey in the car and the (almost) final scene where sign language conveys emotion and the meaning of the moment in a better way than any speech.
