Star Wars The New Hope was the first movie to be release in 1977, this movie change the way movies where made. It brought something new to the viewers eyes, it show us a new world. Later came Star wars Empire Strikes Back and this movie is one of the best movies in history ever made it is number 4 in IMDB not only it had space battles it had comedy, romance and action. In this movie the bad guys win and that is what makes it so special. Later come the Return of the Jedi where are heroes win the war and celebrate as family. 

Later came the precludes where they show us the story of are hero's father. How he change form being the hero to became the villain. These movies where good but not as great as the first trilogy, me personally I love them all but they are not as great a the old ones. You should also go see them now because the new installment will be coming this December Star Wars the force Awakened .
