Actually, this idea reminds me of the ending of Rocky. The original ending for that film was to continue after the fight, showing Rocky and Adrian in the empty arena, all the audience gone, some janitor sweeping up, and they would walk out the door back into anonyminity after this one night in the spotlight. But the most important change came in ending the film just before this, at the pinnacle of Rocky's victory--the idea being that we are freeze-framing on this one moment of his life when he will never be happier, that everything in his life had been building to that moment of happiness and everything after it is downhill, so we freeze-frame on him in absolute bliss and immortalise that moment in time.
That was the thing the prequels never really go--having an actual fall. I mean yeah Anakin is sort of a good guy that became evil, but its so much more tragic if he's actually a hero, the way we were told he was supposed to be. Theres nothing really heroic about Anakin in TPM or AOTC--he saves the day as a kid by complete fluke, then rescues his mom because he's obsessed with her, tries to rescue Padme but he's got an even bigger obsession with her, and tries to rescue Obi Wan but after all the arguing and ordering in the film theres not much emotion there and he fails to do this anyway.
