David Finkelstein wrote a wonderful and on-point review of Onikuma, which has been published on Film International! You can find the full review here.
The film, with its open-ended, poetic sequences of metaphorical action, presents a field of possible meanings, and each viewer will be able to build their own interpretation from the experience of watching the action. Cecchet has used consummate artistic skill in rendering these actions into a wordless assemblage of images and sounds that have the precise force of myth: the ability to take our primordial fears and transform them into legend.
