Started this series partially because tits, partially because it seemed to be a Lovecraftian style suspense. What we got immensely disappointed me, but let's not dwell on that. Let's talk about this awful final chapter.
Ignoring everything else that built up to it, which was a trainwreck on its own, if you look at this chapter by itself, it still sucks. Yukiko appears with no explanation, and no one questions it. Ai's dead with a token explanation and there's no build up to it. Everything just sort of gets handed out with no lead up or anything. It just happens. We could've had Makoto slowly coming to terms with Ai's death and the fact that he'll never see it again, but he just sort of shrugs it off. We could've had an emotional reunion with Yukiko where both parties are glad she's alive, but she just shows up. There's no soul in it, and that's *awful.* The author just fast forwards 2 years into the future to bypass any and all consequences of what happens so that he doesn't have to struggle over writing it. No emotion, no effort. Makoto just got over it offscreen and now he's happy. Deal with it.
