In the hierarchy of intelligence, the victims generally rank lower than the smart horror movie villains they face with very little deviation from that formula. Sure, there might be a final girl who figures out how to best the villain and end the movie, but the antagonist always tends to come back for more in the next installment. The smartest horror movie villains even manipulate their prey into helping them further their cause, as in the case of Samara Morgan in The Ring 2. Others perfectly set up their traps and narratives to span years of deadly games for a growing circle of targets, just like Jigsaw.
When these scoundrels step up their game from lumbering single-mindedly towards a randy teenager to instead playing mind games that leave both their opponents and the audience in awe, it's a triumph that should be celebrated and singled out. It's no coincidence that the most likable movie villains tend to be among the most erudite and cunning as well, especially since they both dazzle and horrify viewers with their sharp wits and weapons.
