A lot of what the media usually does blends into the soft left message. Curiously, a lot of "right wing" adventure films are loaded with "left wing" messages by the choice of villains. Kevin Costner's done a lot of that, though it often backfires. Movies thrive on dramatic tensions and oppositions, and the acceptable kinds of villains become ever more restrictive. Many women's films are feminist and therefore generally liberal. The case with youth movies is similar. The bad guys are always going to be the "uptight squares." Smarmfests with Whoopie Goldberg and Robin Williams. The Seventies paranoia thrillers also fit the bill. And Spielberg. Are his movies liberal, or just escapist?
