I was referring to the rise of commercialism in film, which did occur and firmly root itself in the 80's. There were numerous handovers/buyouts/collapses in the late 60's up through and around the mid 70's primarily due to the replacing of the old guard. Of course starting with the massive unheard of box office returns of Jaws, the climate began to change dramatically. By the end of the 80's we already were in the days of independent producers who did nothing but cobble together the most exploitative product for maximized profit. Not that this is a bad thing, but there has to be at least some moderation.
I've never felt that the 80's had as many classic titles as other decades, but maybe it's just me. But the films produced then are unbelievably superior to the amount of schlock we endured for the ten years of 00's.
