3. Bakemonogatari

Quick Pitch: Bakemonogatari is the first entry into this beloved series. On the surface, it follows Koyomi Araragi as he helps various girls who are suffering from supernatural ailments. It’s also filled with clever Japanese wordplay, abstract artistic choices, and a non-linear story.

Quick Pitch: The 2009 rebroadcasting of Haruhi Suzumiya is the definitive version of the anime since it KyoAni added 14 new episodes.
