Original trilogy, then read the prequel novelizations. Or watch The Phantom Edit [http://en.wikipedia.org/wiki/The_Phantom_Edit] and then... nah, there was probably no way to cut episodes 2 and 3 into something more watchable. Hayden Christensen's Anakin was just too cringeworthy.
...actually, the guy who made Star Wars Episode I.I The Phantom Edit apparently also made Star Wars Episode II.I: Attack of the Phantom [http://fanedit.org/ifdb/component/content/article/79-fanedit-listings/fanfix/239-star-wars-episode-2-1-attack-of-the-phantom]... reputedly, it cuts 38 minutes of stupid, just as the first one cuts 18 minutes of stupid...
So maybe IV, V, VI, I.I, II.I, Novelization of III.
