The point isn't that Hollywood has no influence. It's just that its influence is agonizingly hard to predict or dismiss as unthinkingly liberal. Studies of "All in the Family" found that viewers in America, and around the globe, took different lessons from the show based on their politics and cultural norms. Despite Norman Lear's liberal best efforts, many found Archie Bunker more persuasive than his "meathead" sociologist son-in-law. HBO's epic series "The Wire" was a near-Marxist indictment of urban liberalism and the drug war, making it quite popular among many conservatives and libertarians. The popular BBC series "Downton Abbey" is shockingly conservative in many respects. The aristocrats are decent, compassionate people, and the staff is, if anything, more happily class-conscious than the blue bloods. And yet, as far as I can tell, liberals love it.
