Don't get offended by racism, sexism, homophobia etc. Triumph if the Will and Birth of the Nation are amazing films to watch.
What offends me, is any film with an anti-intellectual agenda. Any film that portrays the act of thinking as something horrid and to be ashamed of. Forrest Gump is a good, literal example but most action blockbusters fall for it too. See, JJ Abrams Star Trek.
