“Five adults must face their past sins when they are forced to deal with the vengeful spirit of a recently deceased woman whom they falsely accused of abuse when she babysat them seventeen years ago.?

Five adults is too many main characters, even for an ensemble, in a? logline for a spec script.? ? Better to narrow it down to 3 max.? Better yet, narrow it down to 1, formulate the logline with one designated protagonist,the alpha character who? influenced the others -- as supporting characters -- to? participate in the false charge.

>>>why should we pull for the lead character to succeed

In a horror flick do we always have to be pulling for the lead character, the protagonist.? Horror stories often entail the notion of dramatic retribution, unpoetic justice --? what the protagonist has coming to him because of his character flaw, because of his dramatic sins.? Can we be pulling for him to get the justice he richly deserves -- but has been able to avoid?? IOW:? horror as a tragedy.

fwiw

There is a lot of backstory in your logline...

Who is the lead character and what must the lead character do to stop the vengeful spirit of the babysitter?

(On a side note, why should we pull for the lead character to succeed since the lead falsely accused the babysitter of abuse?)
