I personally don't even favor golem's CGI much. he still looks incredibly, for lack of deep thinking for a better word right now, translucent and pale in comparison to any real figures. I would've opted for a heavily makeup'd actor instead. I think the same look could be achieved. from my perception nothing about the skin, eyes or hair on golem feels real. I also notice the CGI when it comes to things like catapults knocking down buildings and such. maybe pariculatly because the computer animated dust looks very fake, but overall I believe that CGI must be used as sparingly as possible for best results. It also makes the inventive mind lazy to always look to computers to draw an image rather than figuring out how it can actually be done.
