Is there any superhero scenario more tried and true than stopping the town reservoir from being poisoned? I can think of three Batman stories alone based around that concept. Thankfully, while the set-up of Green Arrow #23 may seem somewhat familiar, Benjamin Percy offers more than simple action and adventure. His command of the characters and dialogue make everything old seem new again and it's a real treat to see the interaction between Red Arrow and Arsenal. Roy Harper fans will also be glad to know there is confirmation that he has some kind of history with Cheshire in the Rebirth reality but no details are given here. Hopefully that tale will be told sometime in the near future.
Juan Ferreyra's artwork continues to amaze. I'm particularly impressed by his use of negative space and color. The above page is a fine example of this, with the muted background colors serving to make the reds seem all the stronger while further enhancing the aura of sorrow blanketing the scene.
Final Analysis: 8 out of 10.
