Biggest problem with both changes (which I don’t think everyone consensus likes OR dislikes - but trying to find a consensus in Star Wars fandom is like trying to find a rose growing at the bottom of a sewage treatment plant)
McDiarmid replacing Revill: The makeup on McDiarmid isn’t very goooooood, and the dialog changes are just extraneous additions. Styrofoam peanuts.
Christensen replacing Shaw: It’s literally a headswap from a costume test. That’s bush league. Hayden isn’t even ACTING in the scene.
I am wondering if, much in the same way McDiarmid has replaced dialog in Rebels while working on TROS, they’re going to re-do Christensen’s appearance at the end of Jedi so that he’s actually ACTING in the scene? But I guess that’s really unlikely now that we’ve seen the 4K masters and that shot hasn’t been re-done at all.
What is your opinion on Adywan’s version of the Emperor scene, in which he edits his face to match with his appearance in Return of the Jedi and the dialogue to match with the original?
