It's interesting that the author tries to take a more nuanced approach to Pop Art, and he does an outstanding job at contextualizing and putting it in it's context in Art History... But the author's personal analysis feels unflattering and hypocritical.
At one point, the author condemns how male and straight dominated the movement was, then he says it was actually a very diverse movement, but then he'll be laser focusing on analysing just 2 artists out of this "diverse" movement to claim the movement was politically subversive.
But that part is rather short, and it's worth a read if you want to see Pop as a movement well versed in it's predecessors instead of a random sore thumb in art history.
