For those of us who were in our 20s when she was on top, this is a remarkable film. Frankly, her personal life on which so much of the film focuses was a complete mystery to me, and I had to scan her Wikipedia bio to check how true to life the film is.
I am sad to learn of her last years and struggles, and her recent passing. This film honors her contribution - and as such, is not judged solely on its creative and acting authenticity. Thus, my 5 star rating.
