I've seen this movie a long ago. This movie is dumb like all feminist dumb.
First a deaf girl (No offense) becomes reason for death of younger bro. She was trying to be cool there by letting him keep his rocket toy which was forbidden by father and becomes the reason for his death.
And after refusing to understand the struggle of his parents, she becomes the reason for her father's death too.
What a bulxshit.
Some scenes are really nice like dancing on imaginary song, father-son conversation. But they are destroyed by the idiotic behavior of girl.
