I would say it’s disappointing but I don’t even want to give it that much energy. Disjointed plot where we spend time floating between several different settings, some of which  seem less useful or worth attention than others. The characters were either unremarkable or not likable, often because they seemed contrived. I don’t know people who talk/act like them, particularly Grace and Yuki. The dialogue was equal parts clunky, corny, and maudlin. Would not recommend.
