My opinion is a bit complicated. I agree with the majority of Star Wars fans that Empire was the best movie overall. But Return of the Jedi is still my favorite. I absolutely love Luke's character in that one, and I love the brother-sister back-and-forth beween Luke and Leia. (Even before he tells her, e.g. "I see them, wait, Leia!") So even though I admit Empire to be the best one, Jedi is my favorite.
