Here we are, watching the hero chasing the villain down. We see the hero dodging the countless bullets that the villain is generously firing towards our saviour. Here, the villain tries his utmost to kill our hero, shooting 1009 of the 1000 bullets at his disposal, but ultimately fails to even scratch our hero in pursuit. Here, the villain doesn't care if he kills the hero, heck, he would even be thrilled to be rid of the hunk.
But then, later in the movie we find that the villain has caught the hero and has put the gun against our protagonist's head. Here, we find that our antagonist has forgotten all his desperation to kill off our hero as quickly as possible. Most times we see the villain elaborate his master plan to his adversary, or explain to the tied down actor the justice of his actions. Sometimes he even manages to cut a deal with the hero and releases the hero just like that. Sometimes, the villain remembers that he actually NEEDS the hero alive in order for his plan to work.
Do you see what I see?
