This has literally become one of my favorite graphic novels. It's a damn masterpiece! I really love the art style, the action scenes, and it especially 'flows smoothly'- the composition, the amount of dialogue/bubbles per page... Fantastic! But most importantly, the story, the themes, and the message. Spot-on. The background/extra content in the end of the book is also very epic and useful!

(Edit: Forgot the "favorite", it's truly one of my favorite graphic novels)
