Hollywood still struggling with how to best use 3D technology

James Cameron is the best Hollywood director in the world

I agree with Spielberg in that the 3D should be used in a way thoughtout process and not just as a money maker. Most of the live action films presented poor 3D usage or the rendering wasn't as good compared with the animemated type of films, plus 2D to 3D conversion of animeated films are much more pleasent rendering of depth.
