If its enough to get my 19 year old daughter (who already has massive respect for the classics) and my 15 year old son to sit though it and experience the story. Then I say have at it.
That was part of the Lucas excuse for all of his Special Edition changes (along with "matching" the visuals to the then-forthcoming "prequels"), and what happened?
Three terrible versions of Jabba the Hutt (the cut scene) appearing less realistic than the full size puppet made in 1982. After a try in the reissue, and twice on home video, they could not create a realistic Jabba, or even try to match it to the design of the puppet.
Slapped in creatures obviously not in the same frame or believable scale as the filmed material (Mos Eisley introduction), not to mention the CG lacks the film grain of the 70mm negatives.
Cityscapes (Cloud City, the shoehorned Couroscant in Return of the Jedi) with all of the realism of a video game.
Was it worth it? Aside from the special editions drawing in original fans (who were going to see the "prequels" in any case), I doubt it was worth the flood of criticism he recieved for the changes.
