Yeah, there are things that stick out painfully now when I watch the saga I-VI, I must admit. Particularly the Leia remembering her mother scene, Luke's feeling in ESB that Dagobah is like "something out of a dream," and the difference between the look and actions of Palpatine between the updated ESB scene and in ROTJ. Those scenes always seemed like they were referencing something big in the prequels, but turned out to be vague, mysterious, unanswered questions that don't have an acceptable answer, now that the prequel trilogy has come along. Damn. I'm being completely honest here. Wow.
