JoeZhang might be talking about the novels featuring the Yuuzhan Vong invasion of the galaxy. They were set about 25 years after ROTJ and created a real division between many fans, some loving the idea of a threat even greater than the old Galactic Empire and others not liking the "Borgification" of the SW universe with some giant, collective alien threat.
The concept was alright. Having exclusively Dark Jedi or gangsters as villains was very old hat and the Vong were a serious outside threat akin to the Dominion in DS9.
The Legacy era was a real step backwards though. A cowardly return to the same old Star Wars formula.
