This film illustrates the bleak loneliness of a lost man. The music is beautiful. The images are fitting and symbolism on mark. It is sad, but not depressing--for me at least--because the sadness is identifiable inside oneself and, therefore, the film acts as a warm embrace which makes this viewer feel... less alone in the world. Maybe it was just my own heart beating, but at least I could feel it happily for a moment. And did I mention, really funny too.
At least check out the soundtrack... Oscar Isaac did an amazing job.
