Personally, the only thing I actually actively liked (I didn't *mind* the rest, but I certainly didn't see any of it as necessary) about the SOT (Saga Original Trilogy) was the FX cleanup, and the new CG ship material for the Battle of Yavin, as the original motion-control work, although great for it's time, is a lot more dull compared to the SOT Battle of Yavin. I loved seeing the matte lines around the Rancor completely gone; it was a real pleasure as an FX buff. But those stupid garbage mattes around the ships were atrocious!
So, I only think we're getting "Pristine," not "Cleaned up," because I take "Cleaned up" to mean effects improved also. But I would LIKE to have the FX improvement of the SOT w/ the new Yavin battle footage, though I accept it ain't happening.
