the extreme aspect is interesting. if we measure our fantasy, which is portrayed by books and moving pictures, it would seem that the boundries of what is considered to be extreme continuely gets pushed.

Orginaly Vampires and Werewolfs were quite grotisque and scary now there childrens ceral and stuffed animals. So that which you measure as extreme, now will be reality prime time tv some day, maybe.

As a society our depravity knows no depths but, from our animal point of view, there may be a point at which society is repulsed. Interesting it could be that which begin as a stave off of the darkness becomes the darkenss against which we must defend.
