One artist per page, with a letter from Batman to Catwoman and a letter from Catwoman to Batman. Further adding to the disjointed feeling is that you get each letter a page at a time, alternating between them.
Wasn't really happy with the letters: not enough revelation and it felt like killing off space for the most part.
Not happy with the ending, either.
Hopefully this series will get back on track starting with issue 51.
