This generally lines up with capitalist profit-seeking making everything worse, more vapid and bland. I agree with him largely. Mainstream shit is dumber and dumber. Doesn't mean great stuff stops getting made, it's just not part of the equation in these hollywood juggernaut board meetings.
Anecdotally I've had young adults burnt out by work and stress explicitly state they want easy brain dead shit to consume. Hard to argue with that honest perspective.
