Bullshit! Tell me how much the 3D technology has matured in 120 years. Besides the number of pixels and quality of color what is new? You still sit there with stupid looking uncomfortable glasses on making believe you are 'immersed' in the film.
It's just another recycled gimmick that has been advertised to death and the ignorant masses have bought it.
Again.
Bullshit.
So you don't care about visual presentation. That's your cup o' tea.
Previous attempts at 3D, both from a technology standpoint and the art direction to showcase it, have been pathetic and boring, hardly worth the view.
Avatar did it the way it should be done. Sure, they took advantage of the tech to showcase things flying or floating out of the screen, but in general, it was about depth and dimensionality... something we see in real life that is entirely missed when looking at a 2D screen.
Some people like to be drawn into a movie. That's why some movies, forgetting about the topic of 3D, are better enjoyed by different types of people. Some just like a movie to simply be entertaining, not looking for anything more, while other people like it to be an art showcase of human behavior in a grounded-in-reality fictional world.
I like both types of movies. The ones that are trying to go for more than simply mindless entertainment, are the types I'd enjoy complete dimensionality and a sense of real depth to the picture. If the audio, picture quality, on-screen performances, the characters themselves and specifically the plot, all line up, together with a well-crafted 3D experience, it just further completes the movie experience.
Is it necessary? No.
Are movies that aren't pure mindless entertainment necessary? No.
