Frame Rate
How many frames per second does it take to anger critics?

The issue for me has nothing to do with the math. It has to do with the psychology.
When I'm watching something in real-life, there's a certain amount of blur to it, as my mind can only focus on one individual detail at a moment (like everyone else). When I'm focusing intently on someone's nose, let's say, the rest of the "scene" gets a slight haze to it. When something is moving, motion blur does the same thing.
And matching the "frame rate" of the human eye is a flawed idea, anyhow. See, in real life, as your eye tracks movement, you're not getting a consistent frame rate. Every time you move your eyes, your brain shuts down input from your eyes during that split second while your eyes are moving -- this is why you don't see images "drip" or "smear" from one to another. Your brain fills in the gaps and grows accustomed to the out-of-focus elements of the scene, especially during relative movement.
When watching in a very high frame rate, a lot of that blur is undermined. The result is that
actually look less natural -- you become more aware that you're watching this scene from a greater distance, and that it's through
someone else's eye. Basically, your brain buys the illusion better when
it fills in the gaps itself (think
Inception).
