News flash. Lucas is not creative either. Midocloreans were ripped name and all from the Parasite Eve anime manga. Episodes 1, 4 (and 7) are remakes of The Fortress. The only really ground breaking and original movie in the entire main series was mostly written and directed by someone else, unless you want to count Johnsons feminist deconstruction shitfest Ep8. Ep7 might have lacked creativity (JJ is mainly a remake magnet anyhow, so no argument from me at all), but Star Wars in the cinema has never been innovative in its storymaking, either. World building it has some legs, but the pre-quels world building was mostly comic relief droids, gungans, and Lucas preaching about "democracy" to the audience.
I will throw you a bone here and say there is one way to watch the prequels and enjoy them. If you approach them from the idea of one man coming in and driving a bunch of corrupt people and religious kooks with too much influence over the society, to replace them with a more efficient and defensible civilization, they play differently. Basically, if you watch them with Palpatine being the hero for ridding the galaxy of a corrupt government, incompetent Jedi order, and insufficient military/law and order, then they are much more entertaining. And ironically enough, the first drafts of Palpatine back in the days of Ep4 was that he was just some smart dude who knew how to use the force and played on the Sith myths to climb to power. That would have been much more interesting, but Lucas bitched out and turned him into a pure Sith cartoon rival religion bad guy instead of the potentially grey are villian he could have become.
