The real problem with 3D is that all (real, not CG) cameras have a depth of field - a certain range over which the image is in focus. This is great in a 2D film to focus the audience's attention on something, but the 3D setup just begs the user to focus on what they think is important, so you end up focusing on some fuzzy object instead of the subject. In other words, depth of field replicates the fuzziness of your peripheral vision, but 3D asks you to look into and around the scene. It's a view mechanics uncanny valley - and I don't think they can fix this as long as there are flat screens.
