Offering up oldies to younger gens is also an option. I’ve seen movie forums with ages 20-30 and at least once a week someone sees “Master and Commander” for the first time and is blown away by it. That’s a gateway into traditional hollywood films like Mutiny on the Bounty, Captain Blood, 20,000 Leagues, etc. The argument doesn’t have to be “back in my day movies were better.” It becomes self evident through exposure. And exposure comes from championing the greats.
Masters of the Air on Apple + is really good.
