Luke Halliday writes:
"Sometimes a film doesn’t have to be all that logical, sometimes being fun is enough. Such is the case with Library Wars, a live-action adaptation of Hiiro Arakawa’s high concept action-romance novel of the same name (which has also spawned a manga and anime). The film strained credibility with its preposterous concept of a world where censorship has gone so far that libraries have taken up military retaliation against the government agencies that seek to burn the books they hold so dear. It is enough to raise an eyebrow or two, but what Library Wars succeeds with is its sense of playful fun that underpins the more ridiculous aspects of its story."
