One of the coolest things about watching the OT used to be imagining the backstory and how it ended up that way. Sort of like a great book that you imagine what the characters look like-- then a crappy movie is made from the book, and your mind is cluttered with the images of the crappy movie. That's what happened with the prequels. Now it's like, oh-- so Darth Vader, the most icy, scarily cool bad guy in the universe, started out as a whiny mop-top, grew up as a whiny teen, flipped to the Dark Side in a split second, and became a whiny murderer? Mmm-kay.
It's annoying that GL claims that Ep. I & II "had" to be boring, drawn-out setups for what happens in Sith, like there was just no other approach. BULL! You're George freakin' Lucas! Do what you want, and if you're gonna make backstory flicks, fill 'em up. They didn't "have to" be fluff. There was a pretty damn good starting point and endless possibilities with the OT as a 2nd trilogy.
