I hate 3D. It was a scam. The movie isn't better, or more high resolution. It barely looks 3D.
technically speaking: how can a screen which is always 2d, even with 3dd animation, ever project something which appears anything but 2d? Ask the people who have been making movies for the past 20 or 70 years.
The quality did not improve. I hate 3D movies.
They looked 3D already. There was no flaw with the original image. They can just as easily make a 2d Image (regular [no optical]) appear to be 3D by animating it to dot he same thing.
