Star Wars - The Empire Strikes Back .Contains the main principles of the Jedi gospel taught by Yoda, the great master. It has a dark tone and struggles that places one to associate with realistic human experience. It flows with failures and how overcoming takes persistence and faith. Alien battles with array of fantasy machines and ships were produced with tedious detail in making it believable. When I watched this in 1980, AWESOME , they were decades ahead and nothing even close to this on or before 1980. (except maybe the first Star Wars movie)
