Also, the Vader reconstruction scene was inconsistent with the OT in that Vader was shown to have no problem breathing without his mask. In ROTJ we're told he'll die without his mask.

Gotta say, Anakin writhing on the table in that scene is odd as it always stays in various people's edits. He's screaming. This is a problem as he's clearly not opening his mouth. If I ever do an edit, that's gotta go and be replaced by tortured gasps and weak, dying wheezes.

That will make it more consistent with the OT, and not have that sound error when he is clearly not actually vocalizing.
