The monster is dead, but not defeated
As a youngster, I loved horror movies because after some terror and fright, the monster or villain was always punished and killed. The twist at the end is that the monster is not really dead, but will return to terrorise in the future. Osama Bin Laden was such a villain, except his crimes were real, his terror was shocking and we in this region were the first victims of his dastardly attacks when he bombed US embassies in Kenya and Tanzania in 1998.
