I just watched star wars on blu ray for the first time since the BR release. The CGI in the first three does not hold up at all. I think the JP CGI looks better, you can just see the green screen in the newer SW trilogy. The FX ILM did on ST:TNG and The original trilogy looks FAR, FAR better. In fact in one of the TNG HD docs, several FX guys talks about how superior the ILM methods were in the 80s to any CGI being done today, saying the passing starfield FX blows his minds using the tech they had, he doesn't think he doesn't think any shop today could do as good.
