Saying that this anime is so bad, that it is good might feel overly simplistic and at this point probably redundant, however it remains a pretty accurate summary of my feelings towards this series, I would even dare to say that, aside from Garzeys Wing, no other anime, that I have seen, has rivaled Big Order in this regard.
The OST is surprisingly nice, there are some pleasent colours and the directing is certainly unique, but if you are not delighted by the terrible characters and story these things will definitely not win you over, however if you are, than Big Order might just be the unintentional comedy for you.
