"So much for the 3D movie revolution. The novelty has apparently worn off and Americans are now opting for cheaper, less gimmicky 2D movies, such as the recent huge hit "Hangover 2." And with a recent bunch of bad headlines, shares of RealD, a 3D technology company, are crashing -- down 11% today."

Over at the Business Insider website an article with some industry statistics suggests that, at least in the United States, interest in 3D movies is waning. One of the issues seems to be that few movies are really taking advantage of the unique experience 3D could provide the viewer. While exceptions exist (like Avatar), many movies provide an almost gimmicky 3D experience, one that viewers tire of and are not willing to pay extra for.
