Re: What would you have done differently?
Over the course of the prequel trilogy, I think it would have been interesting to see Anakin gradually losing his humanity, becoming more and more dependent on machinery to keep him alive to mirror his fall to the dark side.
Also, I would have liked to have seen him fall into a volcano (similar to the novelization of ROTJ) and crawl out, seeing more of the hate and disfigurements burned into him (i sort of imagined a scenario similar to the first Terminator, when the T-800 crawls out of the flames and lies on the ground, his flesh burning off). i imagined his supernatural powers from the dark side keeping him alive before Palpatine and the troopers arrive.
