-A Plot to Destroy the Jedi?
I agree there is a repetitive aspect to this scene with the “situation room during Grievous meeting with Obi” scene, but there is also a more layered concern about Palpatine. This scene, placed after the - long - overture was very good to set the mood of an uprising coup d’état from Palpatine. I think you should have inserted it (but I assume you’ll do that for your “real” edit of Episode III).
Yeah, I like this scene too, but I felt that with the war room scene unedited, it didn’t really work, and since this is supposed to be purely an extended edition, I didn’t want to do that. It will probably be in my full fan edit of episode III.
