The Jar-jar kinda "mauled" (bad pun, that) episode I - far as I understood the script, he wasn't originally part of it and was thrown in for "foil" value - I hated him.
The middle three episodes - IV, V and VI were actually quite awesome, and have become, like it or not, a part of our culture, and it takes one hell of a movie to do that.
Of course, me...I wanted to FLY me an X-wing...and LucasArts eventually handed that one to us on a silver platter (X-wing, Tie Fighter, Addons...X-wing va Tie, etc), much to the delight of the now-much-older-crowd who can now afford a computer.
C'mon, admit it, some of us geezers really get a kick out of bearing down on an imperial star destroyer's shield generators with wild eyes and a big nasty grin thinkin "oh yah, this asshole's MINE" as we power through the engine wash to ditch the wing of Tie's zooming up our tail.....
(FYI, don't play me at X-wing vs Tie unless your ego can handle what'll happen to you, been at this longer than some of you been alive, kiddies...)
Episode I does have a few good points, however...particularly one begins to understand the motivations behind the person who eventually became Darth Vader, and especially why he backed Senator Palpatine's play to dispose of the imperial senate (we didn't learn from the Romans either, look at how corrupt OURS are!).
It also pointed out to me one of the reasons Yoda never interfered with Vader, which is apparently because he felt responsible....the "balance" of the Force mentioned in said prophecy was a dark jedi of much power, and the councils pride would not allow them to view it that way - so in trying to defy it, they caused it.
For those with such interest, Episodes VII, VIII, and IX have been published as books authored by Timothy Zahn, and they're quite good (Thrawn makes Vader look like a wuss..) but as usual, the plot-confusing "offshoots" are as worthless as they ever were...the original plot's solid as a rock tho.
