The reason why people often get travel-sick is because the motion of their body doesn't match what their brain is telling them. Either their body is perfectly still while the horizon is moving around them, such as when on a boat, or they are moving and the horizon is not, such as when they spin in a chair.
Too many movies are trying to be clever with their photography, attempting to give a sense of energy and pace, to emulate "reality" or pseudo-documentary footage, by moving the camera in a consciously shaky way, and playing with the zoom back and forth, deliberately framing things poorly. It's transparent nonsense, and only getting worse.
And it makes people nauseous.
In the real world, when your head moves around, your brain still tells you that the ground is firm and the horizon remains in its usual steady-as-a-rock place it always does. But as soon as you watch shaky-cam footage, the horizon is now moving around erratically and unpredictably, while your body is firmly seated unmoving. End result, dizziness, headaches, and nausea.
Here's an idea, you pretentious dickheads. Keep the fucking camera still.
