Not worth spending money on.
I’ve read 3 of Marc Shapiro’s “biographies”, and I’m not going to read any more. The author seems to have taken his information from google, and published interviews, but not spent any time with people who know the subject.
I knew what I was in for on page 6 “Dakota took her preparation for the role very seriously. She read all three volumes of the Fifty Shades odyssey and was quick to find the style and substance to what many high-minded critics had deemed trash”. Really? She read all 3 books? Wow….
The author seems to think very highly of Dakota, and basically wrote a long fan letter.
