So, I have managed to finish watching Avatar 3D last night and I want to share with you my impressions. Regarding the overall 3D picture quality, I would have to say it is great and the best of all live action movies I have seen so far, although it has it's downsides as well. First of all, the 3d depth could have been better, cause there are numerous scenes where it looks like 2d, and I'm not referring to indoor scenes, but to the out in the open ones, like the floating mountains of pandora. These scenes are also not very blurry if you watch them without glasses.
Secondly, as a personal preference, I would have loved to see more pop-out scenes.
Now, to the good parts, what has blown me away and totally impressed me where the colors. The contrast and the colors are the best I have seen in a 3d movie, animated or non-animated. The level of detail is also great.
All in all, it is a great 3d treat, but not for the actual price ( around 100EUR/$). There are much cheaper 3D blu-rays on the market close to avatar, in terms of 3d depth and effects, although the colors and contrast are not as impressive.
