Things we experienced as children, will not, and cannot, be reproduced in adulthood. Our lifelong experiences just will not allow for that. Frankly, watch Return of the Jedi again, and tell me honestly that it is as amazing to you now as it was then. You know in your heart it was not. Those damn Ewoks are no better than the Gungans, the swordplay between Luke and Vader was terrible, and Luke continuously acted like a child playing grown up. However, it's still my favorite of them all.
That being said, the Prequels cannot hold as much nostalgia or fondness for them as the Original Trilogy did. Lucas held true to his formula, just 22 years apart. The story is fine, in my book. I did enjoy seeing how young Anakin became the twisted Darth Vader. Sure, I'd have preferred to have the Postquels (?) to see the aftermath of the Fall of the Empire, with Luke's advancement to Jedi Master charged with the task of rebuilding the Jedi Legacy. Instead, we got to see how terrible of an actor Jake Lloyd was. My biggest disappointment was how whiny Anakin was throughout all 3 movies, and the death of Darth Maul, who I think should have been slain by Anakin in Episode III.
So all in all, I guess my answer is No, I do not feel like my childhood was "raped." I think we have all been so lovestruck with the franchise since we were kids, we expected to have that same reactions with the prequels, but that's just not possible. We've grown up, seen hundreds of movies since, experienced more in our lives than we could have imagined. I do agree that he should have left the originals alone, but that's not enough to condemn the man. I truly think too many fanboys are so wrapped up in their self appointed superiority complexes, that they've chosen to attack the man for what he's done. And I bet those same fanboys own all of the movies on multiple formats, along with many of the toys, video games, and memorabilia. Seems silly to me, really. In the end, the experience is what you want to take from it, and what you want it to be. Me? I'm pretty happy!
