Not hate just tired of Lucas believing his own press. The music was the most consistent aspect of the six and quite enjoyable on its own merits. And Lucas just came to believe too much in the mystique of his creation.
I was 21 in 1977 and we all loved the first trilogy but the second set while alright was just there. Too much forced mystical crap and special effects and not enough of what made the first three fantastic.
IMO, he forgot who he was as a writer/director/producer.

To me all the prequel hate can be forgiven with how great Episode III and the Clone Wars cartoon has been. I do hate Ashoka though. The Force was way too mystical in the original trilogy especially with Yoda's speech in Empire. You can bang on the prequels on a lot of stuff ie Jar Jar, the pacing of the Padme/Anakin love story and Episode I being boring for an hour and half, but mysticism isn't one of them. Symbolism, maybe.
I know budget and blah blah blah but characters like Sugar and Joe randomly showing up one episode and then not being there the next three is really annoying. Use them, or don't, and stop keeping all these plates spinning.
