The movie business is so big, so powerful, so slick, it seems as though it’s never been in better shape. Consider that “30 years ago the summer blockbuster hadn’t been invented, films weren’t equated with franchises, ‘multiplex’ wasn’t a word, and the people calling the creative shots were the artists, not the bean counters. This situation didn’t last long, but it spawned a group of films so satisfying and challenging that many consider the late-’60s-to-late-’70s to be cinema’s best era.”
