Why too much talking leads to death

We all like a good movie. A great plot, sprinkled with strong dialogue, cooked with smart action sequences and glazed with great acting.

How is it that the bad guy never finish their speech quick enough before getting killed by the guy on the floor? On the floor for god's sake. I've seen movies where a rope is either pulled or a switch would be kicked into life and the bad guy happens to be stood at the wrong spot. Either the good guy is a physics genius who happened to rearrange the furniture off-shot or just sheer outragous luck. Even with his hostage intimately close by, he is hit. Why don't they make use of the 3 second window and get out of the way rather than staring and screaming "Noooooooo"?

Another popular scenario is when the "goodie" is in mercy of the "baddie"either hung upside down or strapped to a chair. Why does he escape? We all know about the old paperclip trick when handcuffed. They are usually patted down for guns etc, but what about his palms? When captive, we all know the good guy becomes a smart-arse when about to escape to ensue in a killing spree:

Bad guy - "Now that I got you, I will kill you slowly"
Good guy - "You wish that would happen"
Bad guy - "Ha ha ha.....what do you mean?"
Good guy - "Because whilst you were talking shit for 15mins, I've picked up a gun from that table over there, by secretly undoing my handcuffs, and sitting back down again"

A third common climatic scene is when the good guy is unarmed and confronts the bad guy. Taking his chances, he suggests that the bad guy to throw his weapon aside and fight fairly. Any egoistical moron would read it as question of his courage. Not me. You'd be a fool to drop the weapon. What usually happens? Bad guy gets the life kicked out of him. If I was questioned, I would just shoot and shoot again and then talk to him from afar.

The cheesy line never really helps either. I'm not going to quote Schwarzenegger as he's infamous for his triple stuffed cheesy arse lines. He is the worst non-american who only plays wholesome american characters with the most jaded and backstreet american accent. I'll save cheesy lines and poor actors for a later posts.

Bad guy(s), for insurance purposes kill the wife/friend, launch the missile or transfer the money. Since you've been looking to kill the good guy for approximately 85 minutes, the last thing on your mind is to try convincing him to accept your Facebook request.
