Remember when blockbuster would give studios like a half eaten candy bar and go "make us 50 B-tier movies" and the studio would go "do you want the crumbs or we can pocket them?"
Its the reverse actually. They now go to a guy, give him twenty trillion dollars and go "make us one B-tier show" and the guy goes "can i get one trillion more?"
