Richard Matheson said this quote
“ How shall I typify what happened? Passion play? Somewhat. Weird tale? Indubitably. Horror story? Pretty close. Grotesque melodrama? Certainly. Black comedy? Your point of view will determine that. Perhaps it was a combination of them all... So, to the story. A chronicle of greed and cruelty, horror and rapacity, sadism and murder. Love, American style. ”
