i totally agree that Hayden shouldn't be in ROTJ. It just doesn't make any sense to me. Luke wouldn't have the slightest idea who the hell he was and if suddenly Anakin becomes young then why doesn't Obi-Wan? The whole " he returns to the state when he was on the good side" just doesn't wash with me. If that was the case then he would still be an old man because he was saved before he died and turned from the dark side. If anything then they should have added Anakins costume from the prequels because he never wears the jedi robes like Obi-Wans (Oh my god, i just went into George mode then. ) .
Shaw needs to return as he was in '83
i also don't like the idea of adding in ties to the EU either. Thats one side of Star wars that , even though it kept Star Wars alive during the quiet years, just just doesn't belong in the movies.
