The writing and art are excellent. But these 5 stars belong to the entire book, especially the extras, which make up fully half the volume. There's tons of stuff in there. Sketches/drafts for all the covers, including variants. King and Walta's original pitch for the book. Character warm-up sketches. Logo and text font versions. All the letters pages from the 12 floppies. Tom King's script for all 12 chapters, paired with process pages showing layouts, pencils, inks, colors, and letters for most of the accompanying art. Marvel.com interviews with Walta and King. And an essay about the book by Hassan Otsmane-Elhaou, a comics creator and proprietor of the excellent comics analysis YouTube channel Strip Panel Naked.
