My main problem with 3D is that while it looks sort of 3D, it also looks fake because the focus doesn't adjust as you look around the screen. When I want to focus on something in the background it's very disconcerting that the foreground is still in focus. When watching a 2D movie this isn't a problem because your brain knows that it's a flat image and you don't have to adjust focus. In 3D my eyes and my brain rebel. It's no wonder 3D causes headaches in some people.

The headaches are typically because of bad 3D. The Warcraft trailer before Star Wars made my eyes and head explode for example, and I normally do not experience discomfort in 3D.

The issue is with too much depth. You have two images on the screen, so imagine a ball. It will be on the screen in two places, separated a bit. If the ball is on the plane of the screen in the 3D space, then the balls will overlap. If it is off the screen towards you, then they will separate with the left eye ball on the right, and the right eye ball on the left. Thus you have to cross your eyes when you focus on them. This happens normally when you focus on close objects; your eyes cross to converge on them.

Behind the screen is a different story. In reality when you focus on something far away, it is at infinity, so your eyes just look out parallel to each other. But on the screen, objects behind the screen have the left eye on the left and the right eye on the right. Thus, you need to do the opposite of eye crossing. Imagine trying to point your right eye at your right ear, and your left eye at your left ear. Both eyes move outward. This is not something you ever do, and it's uncomfortable.

Your eyes are about 4 inches apart, so if anything has more depth than the two images being 4 inches apart, your eyes have to look out in opposite directions. Too much of this, or depth that is too far will hurt a lot.

This can be managed if you shoot and cut it properly.
