Star Wars VI has a special place in moviedom. It came out in '77 IIRC. Between '77 and early to mid-60's, movies and hollywood went off the deep end and forgot its primary job is to entertain, not make social statements or make social commentary or foster social upheaval. Entertainment simply disappeared as a motive for making a movie. Me and others responded by simply not going to movies. Why spend money and waste time and when it is over with I was supposed to feel guilty?
Star Wars IV was a glorious return to the good ol' days entertainment. Matter of fact, the discerning viewer would say Star Wars IV was merely a western in space. You know, good, evil, black hats, white hats, horses, rugged individuals, pretty girls, unfulfilled romance, no-reload guns, villains falling down in heaps, good guys are bullet proof, twisting plots, etc. IV,V, and VI are faithful to the original message. I, II, and III's message is obscured by excessive use of CG.
Consider Star Wars to two epics roughly related. Look at them in sequence regardless of which epic you view first.
