But this is not that important in a theater. You can't really move around in the theater except for moving your head a few centimeters to each side. I would think most people don't move their heads around to any significant degree while watching movies.
Also, the screen is really far away and few objects are so close that moving your head would show anything useful.
What degraded the 3D effect for me is when stuff floating in the air move off screen. Its like when you look through a window. Stuff behind the window your brain expect to disappear but things in front of the window are expected to move in front of the window frame. This is the reason I think 3D-TV will not be that good. Your "window" is very small so this effect will be much worse.
Also the shorter distance to the TV will increase the 3D effect you expect when moving your head around.
A side note for us who get subtitles on the movies. The subs are placed "on the screen", with no 3D effect. When there are 3D objects in front of the screen, the subs are still on top of the objects which completely destroys the 3D feeling. If they would have closer objects partially cover the subs, that would be awesome for the 3D effect.
