The 3D in cinemas: positive or negative innovation?The 3D in cinemas: positive or negative innovation?

Returning home after the cinema:

• Wow! That film has been amazing! It's just incredible, and what about the effects of the 3D? Hilarious!

• Really? I don't know... at 30 minutes of the film I was tired because the glasses and feeling a bit dizzy with headache...

This conversation is typical at the end of a 3D film in a cinema. The question is... it's the 3D a good innovation? It isn't?
In my opinion, the 3D technology is not ready yet to put it in the hand of the spectators. It is a fact that putting up the 3d glasses has a terrible consequence: the lost of a big percentage of the film color; so are all the viewers ready to accept a worst image in change of a little more intensified effects? Not in my case.

A second point is the unjustified size of the 3d glasses. Them cannot be smaller... really? Not only about them can be so uncomfortable depending of the viewer, but is tiring to carry them all the minutes of the film.
Finally, is necessary to tell that the 3D film showing all their effects through the bicolor glasses comport a small (or bigger) feeling of dizzy and a headache after much minutes of the film.
So I think it's necessary that the cinema industry prepare or work more in the 3d technology to make it more comfortable and better to the viewers. Until this time comes, I will continue watching films in the usual style.
