How's this for a Satanic horror story:
A freaky divine being wreaks revenge on all of mankind because they refused to listen to his slaves on planet Earth.
With his supernatural powers he murders the lot of them, except his slaves, it's a grisly scene with the majority of mankind, rotting and putrefying everywhere you look. Birds peck out the eyes of the dead and wild animals feast on their flesh. Clouds of flies darken the heavens while the corpses heave with maggots. The stench is overpowering but the demented slaves dance about in triumphant joy, their god hero has brought retribution to their enemies-- even though the death roll includes children, parents, family and neighbours.
So this is ok is it? But film fantasy is suspect!
