My first reaction is quite embarassing, cause I don't think I noticed. I had watched the OUT a few times before watching the SE97 in the cinema, but not enough to have a complete grasp of what was changed, except for the even more obvious stuff like the Jabba-scene, "Jedi Rocks", etc.
Of course, it is worth a mention that I was 9 years old back then. Jar Jar could've shot first and I would've been happy anyway - I was watching Star Wars on a big screen! In the subsequent years, as a realised the original scene was kept from us, I obviously grew to realise this change was anything but inconsequential. But my first reaction was one of indifference.
