Part of the problem is that Theater owners say it costs $50,000-$70,000 to convert a theater room to 3D. Plus they say they spend $50 for each pair of glasses (although I find it hard to believe that the crappy things they handed out were worth more than 50 cents
).
Anyway, the owners are pushing 3D so that they can recoup their investment. My guess is that you will see more and more movies in 3D as a result.
They made the investment in 3D in another attempt to get people away from the HT systems and into their pricey theaters...
What I really want is 3D movies without the glasses...
