Overall I think it was a wonderful documentary. They used lots of rare footage which was refreshing however the real star was Marilyn's words. I wasn't sure what I would think of other actors reading her words. I enjoyed this when they would also show Marilyn's actual handwriting in the background. Partly because it helped to identify what was going on. I admit that I got confused sometimes as to whose words the actor/actress's were speaking as they also read excerpts from Mailer, Miller, Steinem, etc.
Nevertheless, I would recommend it as a high quality documentary on Marilyn that really tried to look below the surface and show her as a real person.
