I can't fault David Finch entirely for this issue feeling like I walked into an action movie twenty minutes after it started. The recent events of the Superman and Green Lanterns books defy easy explanation and Finch does well enough trying to bring the pre-52 Superman, Simon Baz and Jessica Cruz into play. I can, however, fault Finch for the decision to tell this story out of sequence, with the original Justice League members discussing the new Superman joining the team before they meet him.
I can also fault Finch for the atrocious artwork in this issue. The poses are all forced and the facial expressions are hilariously awful. The inking by Scott Hanna and Daniel Henriques is unevenly applied. Alex Sinclair's colors aren't bad but there's only so much you can do to change a cowpie by painting it.
