While the information is relatively interesting, and the use of concept art and archival footage is good. The overall quality of the film making is pretty damn terrible. Not a fan of the director being physically part of the interviews bobbing his head up and down and awkwardly drinking water.
I tend to really enjoy these DCU animated films, especially The Dark knight returns/red hood/crisis of two earth. However Justice League War has to be the weakest of DCU film to date. While the fight sequences were outstanding. The characterisations of our heroes was pretty awful and the plot was more or less no existent. Want a good Justice League origin film check out New Frontier .
