This issue is heavy on action and light on characterization, but it well-paced action. My only problem with it is that Tony Bedard does throw logic to the wind in order to build the drama in one rather important respect. In the middle of the battle, Kyle Rayner stays in sky to battle the Reach spaceships, sending Fatality on to aid the Blue Lanterns. This despite Kyle (who wielded a Blue Lantern ring himself during War of the Green Lanterns) knowing from personal experience that Blue Lanterns need a Green Lantern nearby in order to activate the offensive capabilities of their rings. By the time Kyle gets there, the battle is already all but lost. I know Kyle may be the most inexperienced of the Earthling Green Lanterns... but this just makes him look incompetent.
The artwork by guest artist Tomas Giorello is competent, but too heavily inked for my tastes. The artwork in a Green Lantern title should be bright and vibrant. There is a lot of color here (no pun intended) but it seems that the only reason the color stands out is because everything around it is so dark. Perhaps this was a stylistic choice given the rather bleak ending? If so, it was not a great choice.
