In my own opinion I like Star Wars III & Star Wars VI the best. Because I feel that Star Wars III made all of the episodes make alot of sense after watching them all together again. As for Star Wars VI; I liked the ending conclusion about Anakin Skywalker/Darth Vader.
Even George Lucas' decision of putting in Hayden Christensen as the ghost of Anakin Skywalker. Just because after watching Star Wars III; it kind of makes sense to do so. Since Anakin was torn up as a young man and it was kind of hard to see Sebastian Shaw as the ghost now. Since he had a full set of hair and was a bit big. That is just my opinion. But for repect for Sebastian Shaw; atleast they kept him in the death scene. That was fine.
But; I like all of the Episodes too. Each of them putted in something very interesting & importance into the Star Wars story.
Probably the only thing that I am about now. Is the part where Luke asks Princess Leia about there mother. Princess Leia told Luke that she saw her mother. I don't understand this one now; because
they were both newborns in the end of Star Wars III.
