As a philosophy major who just recently became captivated by comic books (after reading "Blankets"), Action Philosophers(!) seemed like the perfect fit. After receiving and reading it, it's definitely not the masterpiece I had secretly hoped for. However, it is still an excellent book that I would recommend to anybody who wants to know more about philosophy but has trouble grasping the often complicated texts.
The format of Action Philosophers is as such: Each chapter is devoted to a different philosopher, with a narrator explaining the philosopher's thoughts as the panels depict visual aid, either in a picture of the philosophy or a picture of the philosopher demonstrating this concepts. The philosophers displayed are given appearances that parody either their philosophies or their personal lives (for instance, Plato is drawn as a pro wrestle and talks like an unintelligent brute, while the earliest greek philosophers are drawn with traits of the elements they believed formed the universe). While some of the chapters are written as literal biographies, others depict fictional events, either to display the philosophy better (Kant is depicted as a lawyer defending God) or simply add humor (Mill's chapter is a Charlie Brown parody.)
Of the visual aids.. I often found them amusing but otherwise uninformative. Very often a panel that could really help explain things feels rushed, and on more than one occasion a "humorous" picture is given far too much priority on a page. For instance, in Craig Thompson's "Blankets," Craig tells of Plato's "cave" analogy, using excellent images to depict what can be difficult to imagine while also comparing it to a situation the reader can better relate to. In Action Philosophers, the cave scene is depicted as a group of shackled people watching a movie. But the cave analogy represented how our senses made us believe things were real when they weren't, and displayed the illusions as being a part of the truth. The movie analogy may be more contemporary and funnier, but it avoids some of the key points of Plato's philosophy.
The "contemporary" issue is probably the biggest error Action Philosophers makes. On literally the first chapter of the book, the narrator states of Thales "You'd think his mad mental skills would have won Thales some props from his peeps. You'd be wrong..." Certainly this quote was intended as a joke. However, the "joke" continues on for much of the comic. It feels childish, and for a while I took this feel to mean the book was intended for children (until the sexual references convinced me otherwise). After a while you begin to feel like you're being talked down to by the writers. Comic book readers can be mature, and I was hoping this book would better understand that.
On the other hand, while the art serves only to keep you amused, the text provides some excellently comprehensible summaries on the philosophical teachings. Nietzsche was profoundly understandable regardless of his normally complicated teachings, for instance. And while the art style does not show nearly as much effort and style as I would have liked, it certainly isn't bad.
Overall, if you're into philosophy and comics I recommend you look into this book, as it is actually a very accessible way to learn some elementary philosophy before going into the heavier texts. However, if you're a comic book fan hoping to use this book to get into philosophy, or a philosophy fan attempting to get into comic books, this is not your entry level material. While certainly interesting, it does not satisfy as a great comic book nor a great philosophical text, rather falling under "better than average" in both.
