By baby I think he meant that Anakin (19yo) is even more of a whiner than Luke was in the OT. The rough outline of the prequels isn't that bad, Anakin turns his back to the order for love, and becomes a tool for palpatine in his political quest. But it was the implementation of it that turned utterly wrong. The prequels lack the magic, and fantasy of the OT (midichlorians, etc). Lucas also went for another audience, and tried to approach them through foollish Jar-Jar jokes, and by taking in some of the more popular characters of the OT (Boba and Chewie). As for being Lucas's saga I don't think that is completely true, after twenty years the original triloogy is as much of the fans as it is of Lucas. The kids of the late 70s and all the generations that only knew of the Original trilogy should have been Lucas target, they were the ones growing up loving Star Wars, and no in their twenties and thirties they are fierce fans of the saga, Lucas, he betrayed them. He did not look to tie both trilogies, and instead focused on a new 'fresh' story. He failed to unite both trilogies. OT fans were always hoping that the prequels would depart from the OT. Many people were expecting to see Alderaan, Tarkin, etc playing an important role in the prequels. They were let down. Instead, Lucas focuses in reforming (deforming) the OT to fit the prequels. The consequences are not visible now, but from here in two decades people will still talk about the original trilogy, their smart plot, their smart humor, whilst the prequel trilogy will most likely only be remembered as an accident in the history of moviemaking.
