What makes a better horror movie: murderer or monster?

Tools    





Watched Saw again and I thought of making this. I'm hoping to learn some things about the horror genre this way.

Note: I'd rather not have a poll this time since the main focus is comments and comparisons.
Monsters.

Murderers are limited to their human actions and emotions. Monsters are only limited to their creators' imagination.



When it comes to horror movies I goes with monsters. Human movies are not so scary as monster....



An out of their head villain. Somebody who is pure death drive driven. Somebody like Frank booth who has lost that last touch of filter between consciousness and pure id. Something you could conceive as existing rather than make believe.
Frank is up there with the best of the best.
