Yeah...the worry I have is that Indy 4 will have taken some shortcuts due to the CGI availability whereas in the old days, they had to everything themselves.
I think they would keep them in check somewhat, and thats why I love Raiders...its the true pulp serial movie that harkens back to the old serials where everything was done by the stuntman...it felt realistic because the work was somewhat real.
CGI is still mostly obvious, with the great exceptions of Jurrasic Park's dinosaurs, I dont think I have seen any CGI that I can claim as "realistic"...as silly as that sounds what I speak of dinosaurs. There is some kind of dimensional loss with CGI that they still havent been able to replicate and its not seemless when the real actors and props are mixed in with everything else...again, with some bizzare exception to Jurrasic Park. However, I do have to watch that movie again to make sure I know what I am talking about...as I am am just going on the top of my head.
