Ghost Book feels deeply reminiscent of Yamazaki's debut film, Juvenile (hell, even the adorable little Tetra makes a cameo appearance), a lighthearted family romp often dealing with some relatively difficult themes for its target audience. There's an element of Pokémon thrown into the narrative with the film's characters tasked with "catching them all", benefiting this narrative hook is the lovely monster design, stellar voice work by legendary voice actors such as Akio Otsuka and Rie Kugimiya; and their impressive realisation capturing the essence of Etsuyoshi Miyamoto's original illustrations brilliantly. Unfortunately, the characters are all exceptionally one note, despite the cast's rather heartwarming performances they are probably the most laid-back group of ghostbusters ever, often characterised by very limited personalities (I swear Kudo is just a few steps away from being a full blow serial killer) or singular traits. There's no urgency with this film, it just kind of chugs along at its own pace, often leaving room for a nice family dinner despite the race to get home. That being said, Ghost Book operates on a level of childish fun, obvious in its sentiment and simplistic in its messages. However, it makes up for its narrative wateriness with a wholesome vibe you can't bring yourself to hate.
