I had to stop the movie three times (family reasons) while watching it, but in the meantime I couldn't stop thinking about it.
I found something powerful in the gazes of the characters, especially Nik's. He is so expressive, so deep; has a world in his eyes.
He seems halfway between fury and peace, the condition both really seek, like home.
There are several aspects that don't need as much explanation to understand (again, due to gazes, and a few but useful words), so I think this is one of the reasons why I loved this movie.
And hope.
