I thought this book was pretty awesome - does a great job of introducing many psychological concepts while relating them back to the characters. A lot of powerful writing, actually, and the sidebars are full of relevant and interesting information from cast members.

Only downsides - I really don't appreciate the "Sam's anger and Dean's anger are the same" argument. Completely ignores the abusive narrative and powerplays within their relationship. Dean's anger is often outward: because Sammy is too girly, because someone is frustrating him, etc. Sam's anger is reactionary: he reacts to violence from Dean, manipulation from Ruby, etc. They are not the same, and I can't abide by anybody pretending they are.

I guess this is what you get for reading a collection of essays, but some basic concepts were introduced by multiple authors and reiterated more often than necessary. I guess I had hoped the author would remove repetitive definitions.
