No audiences can accept animation. Look at Finding Nemo. Digital animation is the answer to all filmmaking problems. You can put anything on screen. Attack of the Clones did only use digital effects respectivly. Puppet Yoda can't fight. Model ships can't manuver. It would have been hard to find a large number of people who have the same height and walk to play the clones. Men in Alien maskes look fake, with Chewbacca as an exception but George is not doing him digital is he.
