When Anikan is burning in the fires of Mustafar

I really don't think this should be shown, or even needs to be shown. And if keeping Vader's true identity a secret is the goal then keeping this simply makes the task harder.

I'd prefer an uncertain end to the duel - for obiwan and for the audience. If Anakin were to simply vanish over the lava fall with the collector arm it would mean we wouldn't have to suffer through the terrible dialogue of the rest of the fight and the truly horrifying scene of Obiwan standing there watching him burn. Cue sad music and move on.

And switching things around so the Jedi Temple raids [with a suited VADER] happen AFTER the big Mustafar duel might be a lot more interesting.

Oh, and regarding Palpatine on Mustafar - could it be implied that this is merely Darth Sidious - Presented thus far as a seperate entity to the good chancellor?
