I mean after the Sinestro Corps and Red Lanterns were introduced the concept of other Lanterns got old too quick. The Green Lanterns seemed less and less important in their own corner of the universe....~KL~

I thought it helped expand DC's space stories, many people complained that DC was too earth centric and should expand its space based stories like Marvel. me personally, I really enjoy the other colors and it adds an awesome concept of how our emotions play a role in the universe.
