I've seen several 3d movies at different theaters, and was more inpressed with some, than others. At first, I thought it was the movie itself. But recently, I saw Underworld Awakening at the theater, and wasn't impressed at all with the 3d. However, while watching a 3d channel at home, I saw the trailer for the same movie, in 3D, and was blown away at the difference. So yes, I would say some theaters don't deliver the 3d in it's full potential.
