DNR strikes back, I suppose. Lucas was probably trying to emulate a video look by DNR-ing things. The Mace Windu shot earlier does indeed look grain-reduced. It's a shame because I thought that TPM might have the best transfer in the set.
Which do you think is more bothersome: the EE and slight cropping of the HDTV broadcasts or this DNR'ed version?
EDIT: I do suppose that we should be thankful this wasn't done to the OT. Maybe Lucas wants to encourage the PT more by having what are, in his eyes, better transfers for them.
