I chose to write about Chucky. As a child chucky frightened me more than anything. I see Chucky fitting under thesis II: The monster escapes. To clarify let me explain the plot a little. So the doll itself isn't evil and doesn't come to life until it is possessed by the soul of a notorious serial killer that was on the run and found himself cornered in a toy store by the police. So the serial killer is shot fatally but before he dies he uses voodoo to transfer his soul into the doll that then becomes Chucky. So one thing leads to another and the doll gets bought by a mother for her son.

So we see the antagonist escaping twice, his first escape is from the authorities and is on the run from the police. When he does get cornered by the police he escapes death.
This helps us understand what Cohen is saying about monsters because we experience a monster that goes beyond the natural and that he can escape not only in a physical sense, but also in a super natural sense making the monster unstoppable or immortal in a way. The monster cannot be destroyed and instead is placed in your home where you should feel safe and is disguised as a toy, which says that nowhere is safe. 
It also makes a statement that the worst monsters are the ones that you don't expect, you become comfortable with the monster and put your trust in it only to discover later what it really is, like how Chucky should be a harmless toy, ends up trying to kill you.
