If only order 66 happened in Attack of the clones. I’d love if Revenge of the Sith focused on Anakin hunting the jedi and having Obi wan
I always had this idea in my head of anakin acting disheveled and a jedi bringing anakin into his hut. He tells anakin “I heard stories, they said you were killed at the temple”.
They sit and talk sharing war stories, anakin asks questions about the other jedi and where they are scattered to. He shares a holocron with Anakin.
Then the tone shifts and the Jedi realises in shock that the enemy is Anakin, he goes for his lightsaber but anakin strikes him down in a flash.
The scene from Inglorious Basterds in the bar, that’s the type of thing it would feel like.
He only becomes suited Vader at the end, but by the end he has given up, he wants Obi wan to kill him, but he just leaves him in the state we see him in on Mustafar, it’s only because of Palpatine he continues to live.
