I just wish he had not wasted precious screentime with utter crap like Jar Jar and the Gungans, underwater monsters and an everlasting pod-race, and moved the film and prequel story along quicker

I dont see no reason why we couldnt have had an older Anakin in all three, and im sure Lucas or if he hired a screenwriter could have got round the issue of Anakin missing his mother and the death of his mother

The friendship with Obi Wan could have been more explored especially if he got rid of the Qui-Gonn character, the manipulation of Anakin could also have started earlier, and maybe seen more of his attributes as the best starpilot in the galaxy and a cunning warrior...
