Sean T. Collins’ year end review of mainstream comics at ComicsReporter.com has this to say about writer Greg Pak’s work on “Planet Hulk” and “World War Hulk”:
Greg Pak is a good, conscientious writer. The run-up to WWH had Hulk becoming a Spartacus figure on a faraway planet, and he really put in the effort of developing the different societies and races there while many writers would have just said “draw some crazy aliens.” That carried over into his pacing of WWH, who fought who and how, the way the characters entered and exited the series and interacted with each other when they were there, and so on.
