What a colossal waste!
It was SUCH a brilliant idea! A fading young tv star and his stunt/wing man are living on Cielo Drive in 1969 when new neighbors move in...
Imagine if Sharon's death had been the motivation for the men's actions. Two different reactions:
1. Rick channels his grief into his acting and turns in a career-changing performance on Stacy's tv show.
2. Cliff shows up at Spahn Ranch to make a more external display of his grief. He could either butcher the family or butcher a bunch of lookouts so the cops can raid the place.
