5. Star Wars (1977) (Dir. George Lucas)
George Lucas fashioned Star Wars out of a personal love for shows like Flash Gordon and the endless array of sci-fi serials he watched as a kid, though somehow (perhaps even by accident, as his later efforts suggest), the young filmmaker managed to craft his own version of said space tales that appealed to an entire generation of children and adults alike. For all its inherent campiness, Star Wars remains immune to criticism: standing tall (even today, where special effects have improved greatly) as the ultimate fantasy adventure, the movie has managed to connect with audiences through its child-like understanding of the power of imagination. The special effects were legendary at the time, of course, but Star Wars works because it’s a movie about great, diverse characters working together, and clings to a world that comes with a rich and complex history.
