This was truly fantastic.
The dialogue was sharp and witty without reducing the dark tone of the book. Plus, The Penguin was great here, a man who wants to leave his mark on the work but not in the same way he uses to, Layman's portrayal of the character shows great promise.
The backup story was also interesting despite that it focuses on two random characters.
Overall, a quite nice first issue for the new creative team, DC should give Layman more work.
