Yeah this is exactly what I am talking about - this is where a movie completely loses me. Like there can be a shot of the people running from a wolf or something toward a door, and from the profile shot you can clearly see that the wolf will close the gap before they reach the door, but somehow they just barely make it. I know they are trying to increase the tension, but it's a cheap trick and would work just as well if they obeyed the laws of physics.
