TPM is a great (and greatly underrated) movie and I support any project that tries to bring us closer to its theatrical presentation. Sadly, we have yet to see a true 4k99 (1080p will more than do), and I hope we will some day. To me, the mood and atmosphere of the film as seen in its original form is something quite different from what we get in all the official releases. Colors, lighting, film grain, the uniformity of image quality throughout the whole thing,… these all play a huge role in how we feel about the story and have a great impact on the mood those movie images evoke in all of us.

Personally, I do not mind the CGI Yoda, but any future projects that attempt to restore TPM from a good theatrical source should definitely retain the puppet as a first choice.
