It seems that the first rule of monster movies is to have a visually striking monster. I think we can all harken back to our first viewing of “Jaws” or “Alien” and remember the shivers that it sent down our spine. One being the fear of sharks magnified and the other an original creation that we didn’t know we were afraid of until it was displayed on the big screen. Even when the monster is successful the next step to effectiveness is to not show it often. Fear is what we don’t know, or better yet can’t know, hence keeping the visual queues to a minimum.
