I rather like how we can break barriers with animation, and make it look 100% realistic as possible. Of course, restraints must be held as well. You shouldn't use 100% realism if its not 100% necessary. For example, the movie Up, or any pixar movie for that matter, what would the bugs in bugs life look like if they were 100% realistic and bug-like?
It'd be more creepy than anything :/
but with things like avatar, you can bring things to life that people only imagined, and its absolutely stunning :)
In videogames (i know someone brought that up), realism can be a phenominal thing! Such as of course Uncharted 2! The game was visually gorgeous, and so was the first for that matter. and i felt that i could connect with the human characters because they looked so human like. When drake was hurt in-game, you could tell by his facial expressions that he was injured.
and for the record, the game IS surreal near to the end, such as the first, which also brings things out of the normal, so its a nice mix of real and non ^_^
