This is a great point. Theaters are pushing 3D because it means more money for them. Apparently Avatar was amazing in 3D, and theaters used that fact to make a lot of money off of underwhelming 3D experiences. I saw Tron in 3D and suffered very mild side effects -- facial tension and a headache that went away after a few glasses of wine. The 3D effects weren't enough to make even those mild side effects worth it. I'm not even sure the 3D effects were a net plus for the experience without considering the side effects. Add a 40% premium on the ticket price, and it was a great deal for the theater and a lousy deal for me. Until the technology changes fundamentally, I'm starting to think 3D movies are like heroin: we'll see a periodic resurgence and decline as the lessons fade away with one generation and are relearned by the next.
