The real problem with adding CGI additions to the OT, is that the plates are over 25 years old. Therefore ANY addition is going to look out-of-place, If GL started from scrach and made a complete re-make of the OT, and thus would be able touse CG more, if would be more consistent with itself, instead of having CG from 2004 and Rubber/Anamtronics from 1977/80/3 which would not mesh together in a beleivable way. The biggest problem with the Han/Jabba scene, if that it is so incostent in visual quality, that it destroys the suspension of disbelief that would otherwise be present, due to the obvious visual differences. That, and that the eye-lines are completely FUBAR.

It really would be better for a complete re-make of the OT than to keep trying to clean up 26 year old film.
