The producers of this movie could've easily hired live actors. The models in my opinion are unecessarily real. Why waste all this money, time and human resources just to "animate" live actors? I'm not saying there is anything wrong with realism but come on fellas this is art we are talking about here. Art does not copy nature. It imitates and re-creates. I think we all should grow beyond this popular clamor for "it looks real". Hey, what is real anyway?
