Anomalisa (2015) online

Michael Stone, an author that specializes in customer service, is a man who is unable to interact deeply with other people. His low sensitivity to excitement, and his lack of interest made him a man with a repetitive life on his own perspective. But, when he went on a business trip, he met a stranger - an extraordinary stranger, which slowly became a cure for his negative view on life that possibly will change his mundane life.
