I think that there is better and simpler argument to how Lucas angered his fans without saying "he raped our childhoods."
Lucas had these three great films. Films that involved technology that was innovative at the time. And, with that he created these great movies. However, in the 90's, he decided to tinker with them and give us the special edition of star wars. Lucas was too unhappy with the wonderment that he originally created and therefore altered it. The fans got upset because they saw that there was something amazing in the original films and were angry that the creator of it didn't see it either. So, on one hand they like the movies and characters etc. But, on the other, they don't like the fact that Lucas had to toy with something that need not be toyed with.
However, I think that since this is Disney we're talking about, this could do fine from a financial standpoint but but be crap from a story/creative standpoint. After all, there are a slew of young Star Wars fans who know nothing of the original saga. And, when you mention Star Wars to them, the first thing that they think of are what we would consider the prequels as well as the Attack of the Clones cartoon on Cartoon Network. So, who knows.
