My pal Gavin V. Murray (cinematographer-for-hire and comics enthusiast) generously lent me his copy of The Superior Foes of Spiderman and I've just gotten through with it. The book is great- just a really intriguing little caper story featuring some compelling characters. I hope Marvel keeps a Sinsister Six movie on the table and uses this as a thematic jump-off point. I think it could fit really well in the MCU, especially in the wake of Civil War.
Lieber illustrates it beautifully as well. I love all of the little visual queues and devices he uses throughout the book:
This is the page I really flipped for though (editor's note: nailed it):
Awesome book. Looking forward to picking up the follow-up.
