Exactly. And CGI has reached the point where computer-generated inanimate objects look almost indistinguishable from physical models. Just watch TFA and Rogue One's special effects reels. Heck, most of the palm trees on Scarrif were CGI, and they fooled me completely.I asume you've seen the prequels right?? George doesn't care about models. He cares about visuals. If CGI is the best toy in town to do that, that's the toy he'll use.
Disney Wars have 99 problems, but the quality of visuals ain't one. I do think they lack George Lucas' imagination, though. I'm yet to see a visual in these new movies that would blow me away as much as the Gungan City, Naboo, or Coruscant blew me away 19 years ago.
