Don't Listen (2020)

A couple and their son move into a huge estate to flip it, but the boy is having trouble adjusting. He's hearing voices that often direct him to draw things and sometimes lie to him in his father's voice. When he drowns in their pool, Mom moves out but Dad has to stay and complete the renovation. And then Dad starts hearing voices.

It's a very creepy and interesting idea, especially because they go a "scientific" route. The Dad requests the help of an expert in supernatural communication, who comes to investigate. But, ultimately, it's a haunted house story without a compelling conclusion.
