Personaly, I don't care if it's not perfect (perfection is really impossible for now, and maybe forever...), it's the design which is the most important for me. Take Watto or Sebulba for example, their designs are real awesome IMO. I like their look, the way they move,... and were not possible to create before CGI. After all, it's good to see aliens who are not just "humans-with-costumes", CGI offer a real liberty in the imagination.
On the other hand, we can talk about abusing use of CGI, but it's another debate...
And about the "'cartoony' or 'computer gamy' touch", it doesn't bother me in SW, just cause Star Wars is space opera, referring to all those "retro space operas", and isn't a scientific documentary (see the sound in space, all the planets which have pretty much the same gravity for people living on it,...).
IMO, CGI are real great in the PT, even if it's not perfect. It's sure, we could talk about the "indispensability" of all those CGI creations, even the indispensability of the PT. But IMO, SW is just fun and entertainment, the whole saga isn't indispensable... but, hey, it's fun and real cool, as well as CGI!
