I had seen a few movie clips from this film on YouTube. Having worked at a McDonald's from 1982?-1985? I was familiar with Ray Kroc's name and story. I gleaned that he had made a fortune off the McDonald brothers, but didn't know to what extent.
Louie and I both found this movie to be really sad. Kroc seems to have been a selfish jerk. He pretty much stole their concept, ditched his wife of 27 years, and made it big. He died in 1984 and at least his wife Joan donated much of their wealth. (Though it seems as though she and Kroc got together despite being previously married to other people. They each left their spouse to get together with one another. Sounds like they were made for one another.)
I thought the movie was well-cast and well-acted. I loved the 1950s cars and clothing. I was heart broken for Dick and Mac McDonald, who seemed to be decent human beings. The nail in the coffin for me was when Kroc opened a McDonald's right across the street from their original store (which they could no longer call McDonald's because of Kroc . . . ). What an awful person he was! Selfish and vindictive.
