Heh, I just think its funny when people point out CG in films as if nobody else could tell.
Fact of the matter is that it is the future, and we'll look back on all of the early CG movies with disdain.
Frankly, as long as the CG isn't completely shoddy, I don't really give a damn if I can tell or not. CG is in practically every movie that comes out nowadays, cept most of the time people don't even notice. Its only when something completely unbelieveable is happening (Neo vs Smiths for example) that we feel the need to point it out. We point it out when its blatantly obvious! Hehe, I've even caught myself doing that.
