Although for the 'archive' version it will be left as is, on my own version I will have to replace that frame for my own sanity.
Stuff I have been noticing is mainly the horrible amount of variance in the colour grade.
The other thing I had never thought about before, then noticed, was a reaction shot from Hamill, but I don't really want mention here as it really does wreck an important part of the film, and you literally can't unsee it once you notice it.
