A lot of Hickman's writing (varying by title, but overall quite a bit) consists of visually, conceptually, and linguistically dense world-building infodumps. The term is generally used disparagingly, but for him — I should say, for him, with me — it works, because
- Hickman's world-building is fantastic; his settings are more interesting than most people's plots.
- Properly used, comics are a great medium for infodumps. You're forced to use relatively short amounts of text, which makes you concise, while the visuals are great both for emotional tone and for the kind of open-ended suggestive-but-not-explained detail that makes you feel certain that the world is real outside the panels and before and after the story itself.
