This was always my issue with 3D movies. My eye wants to jump around the scene and focus on different bits, but only the foreground piece the director intended is actually in focus, so it's jarring. It was worst in Avatar.

Thing is, the same bits would be in/out of focus in 2D movies, so no idea why it doesn't bother me there.

Yup I've long held the opinion that you should be forced to shoot everything at f8 at least if you want to make a 3D movie. It's so tiring on your eyes otherwise.
