The remaster improves sharpness, brightness and colors. Also, the smoothness of action scenes. But depth aspects are the same. This is good (it was a movie with very good 3D), but it could be better (contrary to the most people’s thoughts, there are a lot of 3D movies with better 3D than this one, definitively Avatar is not on the TOP 10). Check out other great titles of The Best of 3D.
There’s an Avatar 2 scene on the credits, the 3D of this scene is clearly better, and this scene uses HFR, which makes you feel inside the submerged scenes much more than 3D alone would do. The 3D of this scene is not taken to account for this review.
