I read up until they got to the Joseph Campbell refrences. Most overused gimmick in criticism. I tapped out at that.
What started as analysis became a tool and now an excuse.
Not to mention he is not a respected name with people who seriously study old myths from different cultures, with those types he is seen as a racist white guy trying to force everything into the same western Europian mold and not taking note of any cultural differences.
So I pretty much tune out of anything that uses Campbell as a source as if he is the end all be all of this type of research.
