Graham has been a laughing stock for decades now, not a single academic considers him to be even noteworthy. He had an audience of conspiracy theorists, and now, unfortunately, conspiracy theorists are more organized and you can make more money off of them so he's having a bit of a career resurgence. It also helps that his son runs a department at Netflix, which also explains why he's been giving a show despite possessing nothing that qualifies him to be an expert on any such topic that he's presenting. I wouldn't even trust Hancock if he told you were the nearest petrol station was. The man has nothing of value to add to academia.
