No thanks. The tampered version of ET is horrible, just horrible. The CG version actually looks worse than the one in three dimensions.
And that's a key thing... the 'solidness' of a model, even an imperfect model, is much better than a perfect drawing that's in fewer dimensions.
And George Lucas isn't the man for the job. Weta, Peter Jackson's lot have long surpassed ILM in my opinion (think Kong and Gollum versus Yoda and you'll know what I mean).
As others have said, Jaws is one of the most perfect movies in cinema history. I still watch in awe at the quality of the script, the cinematography, the performances, the editing... the rubber shark is neither here nor there.
