Spielberg vows to never digitally alter his old movies again

the revised ET is an abomination: ET was a well-made, slow puppet but the added CGI was horrible. Also some changes like "terrorist" or removal of gun were beyond unneccessary.

With the Special Editions I am mixed, they helped Lucas re-sell the product to a new generation. But they also really enhance the experience, e.g. the shot where the Falcon takes off from Mos Icely is so epic that I do not wish to see the film without it. Also all those shots were you essentially just saw blinking lights (speeder/ships etc) in the distance and now you see real crafts are great. The new added Jabba and Biggs scenes are unneccessary, not to speak of Force ghost changes further hamming up the scenes.

The only real mistake Lucas made is that he - unlike Star Trek TOS - did not provide the cleaned up OTV for teh purists next to the special editions  (except in one DVD release, but the OTV looked shit here).
