I'm new here, (I came basically because I wanted to comment on Adywan's awesome revisited project) and I have to say that some of you guys are just afraid of change. How the effects are done in a film doesn't matter, it's the final result that matters. CG artists do a a lot more work than any matte painter or model builder and it is the way of the future. True, computers can never perfectly capture the expressions and demeanors of a living being, but that's what mo-cap is for:

I always thought that the CG in pirates is some of the best I've ever seen. It's true that CG can look very bad but so can models and matte paintings. I'll take a complex rendered CG environment over a matte painting any day. I think some of the CG in Indy 4 is poorly done (why get CG prairie dogs when you can get real prairie dogs?) but they took a lot of time in making the movie nostalgic and old looking, and fans shouldn't bash the movie for being radically different because, if anything, it is TOO much like the old movies. I'm glad Lucas didn't go that route with the Star Wars prequels. What people don't realize is that these movies are just as much for you as they are for new generation of kids.
