IMHO CGI are too intangible. The lighting is off or something. As for stop-motion, I find it charming. I wouldn't dismiss a painting because I can see the brushstrokes. The SE often suffers from too much background stuff. Every scene what chok-a-block full of whirling droids and bumbling aliens. At some point it stops being a living universe and starts becoming a needless distraction. And I don't know how someone who balks at the AT-ATs in ESB because they look fake, can even stand to watch the Jabba scene in ANH:SE.
