Yes, yes, and YES!
The 3D image doesn't "break down", but at a certain size or distance, one can see the difference between 720P and 1080P.
It is recommended that one sit closer for 3D viewing. For example, the recommended viewing distance from a 65" display is:2D
> 8 ft 10 in3D
> 6 ft 07 in
A problem with 3D can be that the 3D effect is broken / cut off at the side edges of the screen. Sitting closer helps by moving the sides of the screen into one's peripheral vision, where this will not be noticed. This helps with viewer immersion into the movie, as well.http://www.practical-home-theater-gu...-distance.htmlhttp://www.best-3dtvs.com/guides/bes...wing-distance/
Of course, these are just guidelines.
