i think the problem is quite simple actually. as with many great artist, musicians, directors, there is a certain creative drive they have from very early on, and sometimes it can last for years, but most will burn out and begin to degrade right around the time serious fame hits them. lucas surely had talent and creativity, but at this point, i would argue that he has lost all semblance of what made him good 30 years ago. and not only lost it but looked at his past acheivements as 'accidents' or incomplete ideas when, in reality, they exist as a certain kind of movie masterpeices. his making of the new trilogy and tampering with the old are just crushing blows to fans who loved those old movies for exactly what they were, not what they could be in 30 years when the technology allows. lucas has officially lost his once great ability to be creative, and i would argue that any serious star wars fan could have made a better prequel trilogy than he has, and i mean, anybody.
