I enjoyed the movie very much, emotionally, intellectually, and visually. It contains no violence or sex or drugs or special effects, and doesn't need them one bit, holding my attention the entire time with the visuals, story, and interspersed words of wisdom.
Howe ver:  some of the foreign language accents made the dialog difficult to hear & understand;  there is unnecessary overuse of swearing (especially the F-word, which is the only reason this movie was rated R).  The movie is balanced with humor and emotion, but most of the emotion that holds you throughout the film, except the final resolution last minutes, is unpleasant due to the exaggerated long-lasting dysfunctional reaction of some of the characters to loss, living in the depths of bitterness and depression for too long.  I will not recommend this movie because of 5-seconds of background narration, which did not add one bit to the side-character it applied to, or the film -- it only turned me off to the movie and stuck in my brain through the whole movie and afterward: the main character's mother of German ancestry, when watching old WWII movies, "secretly roots for the Germans." There would be no "local color" or art if the Nazi's won the war. I don't know of any Germans today except radical skinheads who think the world would be a better place if the Nazi's won WWII.
