7) The Sinestro Corps War
Green Lantern is being left out of next year’s live-action Justice League movie, and it currently looks like we’re going to have to wait until 2020 to see the character back on the big screen. The reboot jumping straight into the Sinestro Corps War (a battle the 2011 version teased far too soon in its after-credits scene) is unlikely, so getting to see it before then in animated form would be a lot of fun for fans.
The massive crossover event by Geoff Johns followed the Green Lanterns of Earth along with the rest of the Green Lantern Corps as they fought an interstellar war against the Sinestro Corps, an army led by the former Green Lantern Sinestro who were armed with yellow power rings and hoped to create a universe ruled through fear.
If handled the right way, this could be a true two-part epic similar to The Dark Knight Returns.
