Weak issue to me. I know Tony chose to have Detective 9 become a Night of the Owls tie in later on so he didn't have a lot of time to work on the issue but it's still no excuse for it not even really tying in until the last few pages. The issue was more about Arkham and it's patients than it was the Owls and that really disappointed me. I know they couldn't have done much here because Bruce is fighting Owls in the main Batman book but that being so I don't think they should have crossed over at all if they didn't know what to do here.
Hope next month is better.
