I honestly don't see any difference. A change is a change. PERIOD. Is the extended version of Avatar replacing the theatrical version? Yes. That's all there is to it. To me, it has nothing to do with mindset, with passage of time, with any of that. He's changing the film and has no ground to stand on to call Lucas out for it. They're equally wrong.

Agreed! Using the passage of time as a defense for Cameron is asinine. He can release his "Special Edition" or Ultimate Cut of Avatar but it looks as if he is planning to replace the current theatrical cut with what he considers to be a better version which would give him no right to call out Lucas! On the other hand if the theatrical cut is still considered valid and isn't wiped off the face of the Earth Cameron can get away with it.
