Well, I have seen Q2's Fall of the Jedi fanedits, and I have decided that the prequels really aren't so bad. They're not not ZOMGFANTABULISTIC like the OOT, but they're really pretty good.
...so long as you watch the right fan edit. L8wrtr's Ep.2 edit is slightly better than Q2's Ep. 2, but his Ep 1 and Ep 3 edits are decidedly worse. You can't use L8wrtr's Ep. 2 with Q2's 1 and 3 though because Q2's has very different ideas on how to improve the prequels (such as removing the droids.)
So this shining-a-turd business about the prequels, for me, isn't quite so accurate. It would seem the underlying story isn't the part that's crap. It's just buried under bad acting by Jake Lloyd, whining by Hayden, eye-rolling anachronisms by 3PO, boring title crawls and poop jokesJar Jar Binks.
