Did you see the original with English subtitles ? Much better than this version. Hanks comes close to Otto but the original guy nailed it. The movie was "A Man Called Ove".
Have you read that book " A Man Called Ove" ? That was the original by Backman. Highly recommended.. I've read all of Backman's books including the Beartown series. Even though A Man Called Ove deals with death and suicide-which runs throughout Backman's books-it has parts that will make you unable to stop laughing as Ove endlessly tries to end his life.
