Cass Eris (cognitive psychologist, succdem/liberal) has a playlist going through the book. She brushes part of outright accepts some anti-communist horseshit, but those should be obvious to you when she does. Other than that, she shows that holding JPB to any reasonable academic standard is a futile endeavour, from sharing information from his patients doing little to protect their identity to making absurd propositions and comparisons all with little to no citations. She also makes it a point to point out all the Freudian and Jungian poppycock Beterson has incorporated into his work.

It's a lot of videos averaging 40 mins so you could limit yourself to 1-3 rules and probably still be far more in-depth than your friend. I don't suggest trying to go through the whole thing quickly, Dr. B's work is quite frequently a mindfuck to think about with any depth, far too much quackery to take at face value.
