Hi, I didn't read all the other posts, so I'll just jump in.
I only have season 3 on DVD (remastered) and it's fun to watch to see what's been changed and all, but I can understand the purists, as we've already suspended our disbelief, and maybe we've seen these episodes many times, so when it's changed, it feels odd.
This goes for the Star Wars Special Editions too. The worst is when it even changes the story to a degree. You already told me what happened 20 years ago, now you go and change it!?
