Malevolent (2018)

College kids run a "cleanse your home of ghosts" scam, but that doesn't mean there aren't really ghosts...

The initial ghost-busting scene is pretty good. A grieving father and daughter are desperate to have the recently deceased matriarch move on. The scammers do their thing but, for the first time, the "medium" in the group really does sense then see a presence. When they take a job at the home where infamous slayings of a trio of foster daughters took place, the danger ratchets up.

But then you see what's going on and it's just weird and silly rather than scary.
