... for films shot with stereoscopic cameras (like Avatar) but to criticize a technology in its infancy is patently unfair. Each new generation of technology has to have it's pioneers or the technology could never mature into a truly superior product. (The first generation of consumer VCRs were pretty crappy too!)

I flatly reject the notion that 25% of consumers of 3D on the big screen get headaches or nausea or they wouldn't pay the premium price for the experience.

The shotcomings you see in even well-done 3D (like Avatar) are still light-years ahead of the old green & red cardboard classes of just a few years ago. Still, the technique of using polarized light to differentiate left-from-right is crude compared to what electronic projection will offer the viewer in the future.

In the mean time, look for live-action movies shot in 3D - that's where the experience is the best. Avoid cheap 3D animation if you can.

But for goodness sake, give the 3D movie industry a chance to mature.

It's one thing to declare that the technology is not mature enough for you to lay down the extra bucks but it is quite another to call this emerging technology a scam.
