As with Einstein, the series is superficial, not to say it's not enjoyable. There is an emphasis on sex (although not totally) because it sells.
Walter Isaacson’s book on Einstein was more thorough, looking at his life in all its aspects and Isaacson made his theories somewhat understandable even for science cement heads like me.
I have always been a fan of Picasso, having lived in Barcelona (and visited the Picasso Museum, although not enough), been interested in the Spanish Civil War and all things Spanish. I also admired Picasso’s stand for refusing to step a foot into Spain while Franco was alive. If you’ll notice, my avatar is from a Picasso painting.
To understand Picasso I’d recommend Henri Georges Clouzot’s “La Mystere Picasso,” which you can see on Amazon Prime.
I have read that Mary Shelley will be the next subject of Genius and hopefully that will be interesting.
