Query: The 3D on the DVD is really bad. Pathetic! Incompetent

I bought the JTTDOTE DVD the day it came out and returned the next day.I only bought it for the novelty of the 3D and was astonished at color shifts during shots, only seldom working 3D and the ugly colors it produces. Truly awful.I saw it in a theater and I think this new 3D is in big trouble if theater owners insist on diming their projectors to save money on bulbs. It was so dark, thanks also to the polaroid sunglasses that must decrease the light by at least two stops (camera reference) I hope Cameron's Avator 3D epic doesn't have this problem.Spy Kids 3D works much better.I can't recommend it. And boy am I disapointed.
