This was one of the better Masterworks in my opinion. Being the 2nd volume, the character of Hulk had already been well developed. Like the Uncanny X-Men books, this books issues all tied together in some way; it wasn't Hulk going out and fighting random villains. Stan Lee's writing is perfection, he writes much more sophisticated than the other writers of his time. Also, the art changes constantly throughout the book. Jack Kirby, Steve Ditko, Dick Ayers, and others take turns drawing.
Kirby's art in the first volume seemed very disproportional and ape-like at points. In this volume, his art, and all the other artists' art is flawless. Every fight scene is depicted in vivid detail. The fight scenes, which this volume seems to focus on quite a bit, are marvelous. Not only are the fights long , but they are incredibly entertaining and not one punch seems to be missed.
I won't spoil the whole story for you, but Hulk fights some great enemies like Thunderbolt Ross, the Leader and his Humanoids, and Hercules. I would highly recommend this book to any fan of Marvel.
