The one thing about Anakin’s ghost that would make me get up and leave would be if he’s evil.
*See any rant of mine about the meaning of Anakin’s redemption in ROTJ, re: why the argument for Hayden ghost about his ‘good self’ dying in ROTS is fundamentally wrong, even if Lucas says so.
I agree, Shaw would be preferred but unfortunately he is one with the force. Hayden is the best option remaining (sorry Jake)- unless they could pull a Tarkin on us.
