A spoiler warning is necessary: a drastic change in tone occurs partway through this methodically deceptive drama. And though I hate to ruin the complex experience of following a rather calm story about a lonely widower as it becomes something else, I feel obliged to point out that the hard-core gore and soft-core surrealism of this baroque morality play may not support any theme, least of all the one spelled out in a vengeful character’s dialogue. Takashi Miike directed a screenplay by Daisuke Tengan; with Ryo Ishibashi and Eihi Shiina. In Japanese with subtitles.
