The medium is the message. If you don't think that CGI have a negative effect on how filmmakers approach the creation of a film you have your head up your ass. Does anyone here think that the great epic blockbusters of the pre-CGI era are not superior in nearly every way to the modern garbage we are fed? Yes, I am including overrated mediocrities like LOTR and Avatar as "modern garbage"
A tool is never just a tool. If you don't recognize that you end up like Mr. Lucas.
