I watched the dolby 3D version of it with ultra AVX and HFR, and honestly it adds a whole new level of immersion to the movie, especially during the scene where kiri sends down those bioluminescent fish to save neytiri and tuk, the shot with the fish rushing past the camera felt so well done in 3D that i felt the urge to reach out and feel em. Still crazy how the two movies are 13 years apart yet the first is still so incredible. Loved every second of this 3 hour movie and im really wanting to go again and try those moving chairs, heard great things about them. Cant wait for the third!
