I feeled it as a great film. For gentle portraits of intense vulnerability, deep loneleness, for paternal patience and gentle help, for beautiful crafted story, for admirable simplicity and for the wise exploration of characters.
A story about frustrations.
About angry and about a man reduced to a kind of Peter Pan syndrome.
One of basic virtues - the admirable acting. The other - precise development of story, with great American novelists sparkles.
A faithful portrait of a life.
And the frame of intense loneliness.
A great good point - the title itself. Like the inspired cinematography.
In short, just bitterness well used.
