For me personally, when the 1997 special edition versions came out on VHS it wasn't long before I quickly ditched the ESB and ROTJ originals. I actually thought the new colours used for ESB and ROTJ looked better and it was only until they did the colours again for the 2004 SE that they it look just plain wrong in my eyes.

The first ANH was a little bit harder for me to budge on, as the original was perfect in my eyes and I wasn't particularly fond of the changes Lucas made to it in the 1997 SE version. ESB and ROTJ changes were more forgiving and I actually liked some of them but again, the 2004 SE went too far and ruined them for me.

It would be interesting to see a comparison somewhere of different screenshots showing the differences between the originals, 97 SE and 2004 SE. I can only seem to find comparisons between the originals and 2004 SE from a lot of places and where I can find some comparison to the 97 SE, it doesn't compare much. Would be interesting to see the 1997 SE planet Hoth compared to the 2004 SE Hoth and see how bad the blue is during the snow scenes.

Also, is it just me or does Vader sound way cooler in GOUT/97SE ANH compared to the 2004 SE version? Sorry if this is a stupid question, I am not totally aware of all the different audio changes made.
