I don't know much about Robert Downey Sr. As I didn't follow his work. But I have watched Robert Downey Jr since he was a teenager. With all of the trouble that he ended up going through, I think it's amazing that he and his father retained a wonderfully close relationship. This is a loving, caring tribute from father to son and son to father. I love that Cat Stevens music was used in the movie. It was wonderful to see Jr's son involved , especially toward the end of Sr's life. I do t know what I expected, but I really enjoyed this amazing documentary. Thank you for sharing your personal life love and sadness with us.
