Drawing heavily from kids' adventure films, ergo The Goonies just minus the gritty edge of the 80s and early Spielberg, Juvenile marks the directorial debut of one Takashi Yamazaki. He weaves together an engaging coming-of-age story primarily following the child characters and invoking a sense of imagination many kids partook in during the early years of their lives, retaining an old-school sci-fi charm along the way. It all feels genuine and is helped by the performances of its cast, although it does struggle to make many of the relationships organic. Its musical score by Yasuaki Shimizu is pleasant on the ears, with a beautiful theme to close the film the visual effects however, are more of a mixed bag. The CGI has aged horribly as was par for the course in Japan during this period but the practical effects work is fantastic, especially Tetra who is freaking adorable. Despite its faults, Juvenile is a competently made movie and an exceptionally charming one at that, capturing that feeling of childhood nostalgia with relative ease, Yamazai had a lot to offer and Juvenile was the first stepping stone to that success.
