Definitely not. John Diggle and Green Lantern are distinct entities in the comics. Green Lantern has specific powers, origins, and adventures that are separate from those of John Diggle.
Well, 'Green Lantern: The Sinestro Corps War' is quite popular. It has intense battles and John Stewart plays a significant role in the fight against the Sinestro Corps. The story is action - packed and the art really brings the epic battles to life.
One great one is 'Green Lantern: Mosaic'. It shows John Stewart's unique journey in building a community on a world filled with diverse cultures. His leadership skills and the challenges he faces are well - presented in this graphic novel.
It depends on your taste. Some people love the imaginative universe and complex plots of Green Lantern comics. However, if you're not into superhero or sci-fi themes, you might not find them as good.
I'm not entirely sure specifically as there could be various aspects to it. It might be about John Boyega's experiences related to the new Star Wars canon books, perhaps his influence on the stories, or his own journey within the Star Wars universe as it's presented in the new canon books.
