Blackest Night

Ever since it was announced that the Green Lantern movie will actually be a Green Lantern Corps one, we wanted this story to be adapted. Even if it will be now, even if it will be later on, Blackest Night needs to happen. This storyline could be connected with everything that has happened thus far in the DCEU, as well as with any number of storylines on this list.

It is so impressive in its scope and features so many events and characters, that it needs to span over several solo and ensemble movies. Furthermore, it can show why the Green Lanterns are actually the protectors of the Universe, being able to handle threats far beyond the powers of Superman and all the others.
