Actually I think the '97 version is overall preferable to the '04 set--it still has Boba's proper voice, the sound mix on ANH is excellent (unlike the pure shit that is the dvd version), Shaw is still there in RotJ . . . there is Luke's scream, though, which the dvd removed.
Damn it. Sometimes it's hard to pick what exact version of the movies is best in everything. If only George weren't so revisionist, we could actually enjoy these movies in peace without nitpicking the details.
