It's worth slogging through Nisemonogatari and Nekomonogatari to get here. Fantastic arcs.
Was the Tsubasa Cat arc in Bakemonogatari not sexy enough for you? Here it is again but in lingerie. And I GUESS some more character development with Shinobu.
Too much inexcusable uncomfortable fan-service (read borderline illegal) to make the neat dialogue worth it. It is important to the overarching Monogatari story, so if you're embarking on it, muscle through.
