First issues of event comics have to accomplish a lot. They have to introduce a conflict, introduce a villain, give heroes memorable moments that bring the reader back to see more, set up side stories that can be fleshed out in other titles, have a big battle scene, and the list goes on.
Infinity #1 by writer Jonathan Hickman and artist Jim Cheung with a team of inkers, colorist Justin Ponsor and letterer Chris Eliopoulos, does some of those things, but in a sort of sidestep rather than a straight-ahead dash. And some of the items on the checklist, it willfully denies the reader. In the end, I wound up liking the approach, but getting there took a lot of trust not every reader may have.
