The Justice League is featured on this film as Lego characters, which makes the film very funny. Anyway, we do not have to be fooled by the appearance, because we are before a history of superheroes like those of truth, that we all know and in which are present a good part of the personages of DC.
Until now, the Justice League had always triumphantly emerged from all its clashes. They had always fought against enemies alive, against their fellows. I say about enemies alive because the enemy of this movie is not alive.
It is BRAINIAC, which is not a person of this or other worlds, but it is a machine. As a machine it is, its intelligence is enormous and can not be killed, because it has no life.
Can the Justice League end this new threat?
