What I Liked: The setting and world-building. Intriguing concept.
What I Didn't: The fact it's really a rom-com. Both the OP and the ED were boring and forgettable. The series didn't really do a lot with the setting created, I felt as if the romcom-military/censorship balance was out-of-whack the whole time. Almost everything else about the series was pretty average fare.
Final Verdict: Toshokan Sensou / Library War neither makes an effort to invoke moral discussion about censorship and war nor tries to be an intellectual military-focused anime. In fact, it's nothing more than an action-oriented, slightly disappointing and uneven Romantic Comedy.
