Gotta disagree with all that. The Gantern Lanterns are peacekeepers. They help people regardless of where the danger is coming from.
That doesn't make sense, especially in light to the overall history of the Green Lantern franchise. The Corps is comprised of individual members. They can't always be together in the same place at the same time. As what happened years earlier, there can be more than one book in the Green Lantern franchise. Hal can have his own solo book, while John can lead a book that includes other Lanterns we don't see all that much.And no you can't split up the GL corps and each single GL, they are part of the same corps !
Why the need to relaunch Hal again when Morrison & Sharp took over?Why the need to relaunch Hal again ??
