Critical reception
James Marsh from South China Morning Post gave a mixed review, stating "Existing fans of the television show will doubtless already have their tickets booked for this frantic and fitfully entertaining continuation, but curious parties approaching Signal the Movie for the first time will be better served seeking out the small screen series first – or even the superior Korean incarnation, both of which are streaming on Netflix." Mark Schilling from The Japan Times praised the action sequences, stating "This cop thriller based on a 2018 Fuji TV series may be gimmicky, but it delivers in the action department." References
