It's beyond my own comprehension of how to look at a movie and not see the acting, script, etc. AOTC is certainly the most stunning in artistry, and its CGI use is rather well done, (though I do admit, the Arena Sequence does seem to overdo it).
But most people would agree that SW has always been about more than graphics and special effects, there are stories to tell and characters to tell them. If movies, or even just Sci-Fi relied on nothing but scenery to sell tickets and win over crowds, then Alien, Star Trek, Star Wars, a numerous other films and shows, would have failed miserably at their beginning.
And to be fair, the OT was visually impressive when it was released. Give it 20 years and people will be criticizing AOTC for its use of archaic computer images and graphics.
