WHY, SCREAM 4?

WHY IS THERE A SCREAM 4?

IS THERE REALLY A REASON FOR "SCREAM 4"? IN OPINION, NO, THERE'S NO POINT IN WASTING A GAZILLION DOLLARS ON MAKING A PRESET FILM. WHY CAN'T WE HAVE NEW STORIES? I HAVE ATLEAST 5, HOW COME NO ONE ELSE DOES? THE LAST PERSON THAT GAVE US A NEW CONCEPT, ROB ZOMBIE (WHO IS A GOD OF FILM MAKING), BUT HE GOT SHOT DOWN. WHY? THERE'S NO LOGICAL REASON.

A NEW SCREAM SERIES WOULD BE GREAT, BUT WITH TALKS OF KILLING THE MAIN CHARACTER IN THE FIRST 15 MIUNTES, WHY?
