Suspend disbelief in that you can't see that the punch never actually landed, or that the monster that ran across screen was actually a man in a rubber suit. When something happen fast at 24 fps it naturally blurs. It is why shaky cam, low resolution footage can be scary. Direct to VHS horror movies could be scary because you could only barely see what was happening allowing your brain to fill in the gaps. At full resolution captured with a high speed camera everything looks a bit silly / fake.
