Other than the fact this is a fabulous, ground setting movie, it sets a standard for a new 3D venue. What I liked best in respect to the use of the 3D was that it was an enhancement to the story, a vehicle of cinematography. There were no frivolous, useless scenes that exploited the 3D just to wow the audience, like objects shooting out with no intention other than to shock & awe. The movie was a Wow all on it's own. Cameron's attention to detail was flawless. This is a "standalone" film that will launch blockbuster film makers into a new genre.
