Why “conservative” or “leftist” art? Why not honest, heartfelt, well-executed art instead? I don’t usually care for art pushing a political view, period.
I think that the best stories involve the use of of timeless ideals...
the good in honesty, the evil in betrayal , the good in faith, the evil in jaded pessimism, the good in hard work and persistence, the evil in shortcuts and taking the easy way, the good in personal responsibility, the evil in greed and jealousy, the good in self control , the evil in gluttony and vice, etc....
I’m not saying that the movies should preach these things but they often use the themes to tell the story. Since these truths are written on our heart, the stories ring true to us.
What people are referring to as “conservative movies” recognize these universal truths and use them in the storytelling.
What people see as “liberal movies” either ignore these truths and try to make up their own truths in very uninteresting ways because they don’t ring true to us or they spend the entire film trying to prove that the way we understand these truths is actually backward.
