For me the problem is that the documentary based on Tom Grant the PI is manipulative. Showing excerpts of phone calls etc. It definitely looks shady. But I don’t think there is a clear case of what happened or they would have made it. It begins with a statement about how PIs usually have skeletons in their closets lol. Weird.
As for Courtney Love yikes I don’t know what to make of her. She would intimidate me. In the second interview I got a cat and mouse feel. She the cat and the interviewer the mouse.
