I would say over 900 instances of visual differences, plus how many ever audio differences. Didn’t we have a breakdown of how many frames were different at one point?
I think pointing out the insanity of 900 changes works for those of us who are already on board about the subject. I think TFN’ers and redditors (i.e., Lucas apologists) and such often point out the minor changes we discuss as reasons that we shouldn’t be taken seriously. If any time is to be spent discussing what has changed, it might have more impact to discuss the more glaring changes, where bits of the films were unambiguously lost in the process. Some of the 900 things, normal (uninformed) people might consider to be standard “remastering”.
