Ranking the Star Wars movies
Episode 5 - The Empire Strikes Back

Episode 6 - Return of the Jedi
Episode 7 - The Force Awakens
Episode 3 - Revenge of the Sith
Episode 1 - The Phantom Menace
Episode 2 - Attack of the Clones
As a cultural moment, one can't beat Episode 4 - A New Hope. At the time, in 1977, the film was simply Star Wars. It was only because of its unbelievable box office success that the other films were made. For strength of story telling, I have to give the top prize to episode 5. The franchise was so strong that even though Episodes 1 and 2 were panned by critics and fans alike, the Star Wars property persevered.
In the years ahead, the films will expand to include a set of films Episodes 7-8-9, the newly released Rogue One that I haven't seen yet, and a set of films around Han Solo. Who know what else they have planned for what appears to be a cash cow for Disney!
