I 100% agree about the overuse of CG, and not using real landscapes. I defy anyone to watch the saga, even the OT/SE 1-6 and not see a jarring effect from PT to OT. The bottom line is one looks computer generated and one looks real!

I often think what would the PT have looked in 1986 had Lucas continued on before the advent of CGI once Jurassic Park broke the mold. I think the saga would flow visually and I still contend there are great, real environments out there in Europe, Australia and Asia that could have been shown for planets on the PT. But Lucas is paying for these film and I believe it is cheaper to film in bluescreen, then pay money to shoot on location.
