Such Luddite thinking. The CGI in the prequels was staggeringly good, raising the benchmark for the industry. Consider: Jar Jar Binks was the first completely CGI main character in a movie (who cares if he was loved or loathed, the technical achievement of that character is something to celebrate and paved the way for Gollum in LOTR); the land battle between battle droids and Gungans was unprecedented and again pushed the envelope; AOTC was the first movie to be made digitally so again that broke new ground, as divisive as that move was; the CGI in ROTS built on the advancements made by the previous two films and raised the bar even higher.
