I think when the day is saved at the end of an end of the world disaster movie or armageddon film, there is great relief and then we thank our lucky stars we are still here! It is good to be able to say "not here not now." But then as for grade B horror films, sometimes I watch them because they can be so silly and humorous and sometimes I watch them because of the bizarre and/or gruesome image. The film industry got in trouble when TV could air movies so they had to make money making grade B sensational films. Is there anyone out there that doesn't want to see what The Blob looks like or The Mushroom People lol But then I can't stand much that is scary human image like zombies--I can't look at zombie depictions, whether ads or movies, I see them and run. lol For me the almost human scary image or alienated human state is too close for comfort. Yet, I do often write horror, but only the type of horror I can stand and not have gruesome nightmares about.
