I don't think, no matter what, the prequels would ever have been what some people expected. Many people expected 3 more films like the first 3, but unless the story took place very shortly before Episode 4, there was no way for them to really be the same. The prequels are mainly the story of Anakin, but the events are about the shaping of the galaxy, and because of that, the stories involve more characters and situations than the OT and it becomes a large spread of players who never spend enough time together on screen to develop chemistry. For example, based on personalities, I think Obi-Wan and Padme could have been a nice pairing of similar personas, but there was no room to explore that with all that had to be told. The events of the PT could have opened to more intimate characters and relationships if the 3 films had been spread out over 6. George's story vision was far grander than 3 films could allow, but at his age and all, that's all he was prepared to make so he did his best to cram it in. What we got was entertaining, but also very different than the OT. OT was really about following Vader, Han, Luke and Leia, with a few others popping up along the way. The PT covered Obi-Wan, Anakin, Padme, Count Dooku, Darth Sidious, the Neimodians, the Senate, the Jedi council, the Wookies, the Gungans, the clone army; it was all over the place, and that's fine. I don't think it cheapens their value to be what they are, but understandably, if your dream was for 3 more OT-styled films, ya, you were let down, but if you put your dreams aside and try to look at it from the director's perspective and understand his vision, you can understand him better. George Lucas has a vision of what the Star Wars storyline is, and as an artist he will never cease to make the realization of his mind's vision the best reflection of what he had inside that it can be, whether we like it or not. In a way, you have to respect him for that; he doesn't care what the public wants, he stands behind his vision, hence not wanting to release the untouched versions of the OT anymore and only doing so as "bonus materials".
