Kubrick’s movies are slow but get better each time you tackle them. Most also have pretty obvious leftwing messages: Spartacus is about a slave revolt (the writer was blacklisted I believe), Paths of Glory is anti-war, The Shining is about American genocide and the horror of the bourgeois family, Eyes Wide Shut is about Kubrick getting assassinated because he discovered Epstein decades early. 2001 might be his most rightwing film? It’s about human evolution and tools and has a strong Nietzschian element, but the film’s writer, Arthur C. Clarke, was not a rightwing dude and was definitely interested in cooperation at least between the USA and the USSR (which is positively depicted in 2001 and 2010).
