The whole point in doing it is to have pointless and overblown cgi dogfights. Emulating the dog fights of a new hope without there being any use of real models or any original thought.
I wouldnt mind it, the space battle is so boring when compared to those in the 4 others with space battles. ANH, while being tied with ESB as my favorite SW movie, is very bleh. It really is an inconsistecy with the saga, even ANH's sequels.
Some people are saying that Avatar is the greastest movie they've ever seen. But i think we can all agree that the plot was very simlistic.
Now imagine SW as beautiful as Avatar. Im not talking CG crap, although its fastly improving. SW would blow Avatar out of the water. Basically every aspect of ANH is better than Avatar. Im not trying to be a fanboy either.
I wouldnt rule out a new and improved space battle, Emperor scenes, or a new duel for the 3D release.
