Not everyone can see the 3D effect (and it's apparently a sizeable
portion of the audience):

For others, 3D viewing results in eyestrain and headaches.
I'll happily take a well-made production with a good plot and acting
any day to a "Bwana Devil" or "Cat-Women of the Moon".
3D motion pictures have been around for nearly a century. Every once
in awhile the technology is resurrected and then abandoned.
Quality writing, production and acting is timeless.
