Why should (all) movies and television shows be about escapism? I'm of the opinion that every movie and television show has some politics, is conveying some message or theme. They don't come from a vacuum. They come from people, people who have certain beliefs, whatever those might be. Granted, some entertainment can be heavier handed than others, though I think some of that is because the beliefs espoused or being 'promoted' in said media conflict with our beliefs. When they don't, then we might think there is 'no politics' or 'social commentary' involved because the beliefs expressed are 'apparent' or just 'common sense' or 'the way it is'. Also granted, some entertainment is more direct in wanting to express a viewpoint whereas others might be half-formed ideas or something in the creators subconscious that takes form, or forms, said creator might not even recognize. And of course movies and television shows are open to debate and interpretation.
To me, the trick is saying what you want to say, in an organic way to the stories and characters, that doesn't ground the story to a halt to make your point.
