Dustin Hoffman is amazing as usual and I really loved the music and the cinematography. It should probably have a PG-13 rating by today's rating, but I think it's pretty normal for older movies that today be rated PG-13 rated PG.
A very entertaining movie with a great story, great music, and great acting. However sex is one of the subjects and it isn't very appropriate for young children. Should be PG-13.
