This clip clearly shows how Quick cuts can make a scene seem quicker and more action packed. Because of the speed of the cuts, it adds to the overall speed that boost of adrenaline this scene is trying to achieve. The quick shots mean that there is little time for the audience to think about or dwell on each shot. Yet when the action stops or slows down, the shots get longer, giving the audience some "breathing room"
dialogue scenes or scenes where there is a lot more information to process tend to have slower shots due to the fact that they are trying to get you to absorb new information; often so the info is fresh in your mind for later on. An example of this from "in Bruges" (apologies for the language...)
