This is probably the best movie overall that I've seen in years, from both a story viewpoint and also the amazing use of 3D in this film - the 3D was used to better effect here than any other 3D movie I've seen.
If you haven't seen this yet, you need to - you will regret missing this in 3D if you wait for the DVD... it's really that well done in this case.
I don't usually see movies more than once, twice at the most for something exceptional... I've been to Avatar 3D three times now with various friends and family, and I'm actually planning to go again before it leaves theaters. Truly an amazing piece of work.
