You're wrong because the beginning of Episode I was pretty stupid. None of it makes any god damned sense. The end of III would have been far, far better if the final duel between Vader and Obi-Wan was more like the
Duel At Ganryu Island and less "jumping on floating things over a river of lava for 30 minutes".
In fact, if Lucas had stuck to his roots of using Japanese Samurai films as his inspiration, then the Samurai trilogy would have been a perfect candidate to build the prequels on, with Obi-Wan taking the role of Musashi.
