It's not frivolous. It’s hard to think of them in such a story. She suffered psychological and physical trauma in Afghanistan. He wakes up and doesn’t know how to live. Dating a black guy. He is disabled and responsible for the accident in which a young nephew died.
And then the film tells how these two unfortunate people rub each other. The process is slow, but in a positive direction.
The spectacle is calm, somewhat tedious, but it is impossible to say that the film failed. Anyone who likes unhurried stories is the best.
