I agree with all that is being said about CGI but in it's defense...

CGI can do things today very well like robots / moving mechanical , windows, wood, metal and all sorts of synthetics very well because by it's nature it is synthetic as an effect.

But as soon as you start to try to synthesize biological things animals / monsters / natural environments i.e. trees it falls over.

But it can do repeatable patterns quite well also like fire / smoke / fog / snow / water / rocks / blood and environmental environmental effects.

It just all goes wrong when it comes to trying to create something that is alive because we can feel that it is dead there is no soul or energy transferred by cgi.

But it does do dead things like real dead things
