Money ruins everything. The good films we all remember were back in the 50s, 60s, 70s, 80s and early 90s before any of the home video stuff really took hold. Yeah, there were some video rentals, but it wasn't the major business then. People still wanted to go to theaters. It would typically be a few years before a feature film hit TV screens and that was after a few rounds of big screens and maybe drive-ins. Generally they were more concerned with making movies than quick money like they are today.
Sure they wanted money, but they knew it might take a few years for a film to pay off. Now, they want a full return plus some in months, if not weeks.
