3D movies are poised to make a lot of money for studios.
The only problem is that there aren't enough screens to show them on.
The other problem, not really discussed in this NY Times article, is that Hollywood is trying to do big specticle films in the format that require a large number of screens to make their money back.
Maybe it's just me, but it would seem like lower-budget rom-coms, horror films and other kinds of teen pics would be the way to go to generate interest in 3d again. And, again maybe it's just me, but perhaps they need some better directors that understand how to set up and shoot in depth so it doesn't add so much to the total cost.
3D's easy if you know what you're doing.
