He made some good movies but not great movies. Apollo 13 slurred the corporations that engineered the space program. Even Gene Kranz opposed that subplot of the Apollo 13 movie but Red Howard held to his evil corporation agit prop (I think it had something to do with “they cut corners” which was a lie).
Just speaking for myself, I don’t mind them doing what they want with their movies, although I see your point about propoganda. For example, I like both JFK and China Syndrome as films, although I don’t accept their premises one iota. In fact I can view both as rather evil propoganda but I enjoy the films.
I think Beautiful Mind was a very good film (also inaccurate in many respects) maybe even a great one, I fell in love w Jennifer Connelly, but I don’t value her political views or R Howard’s.
