Neglected as a child, an independently wealthy young woman spends her time spying on individuals who she considers to be as lonely and isolated as her in this decidedly offbeat film from Japan. The movie initially plays out like a quirky comedy with lead actress Kumi Takiuchi grinning from ear to ear all the time while riding her bicycle, camping on rooftops and taking notes on the lonely citizens she enjoys watching, whom she terms "Solitarians". The plot thickens though when one such "Solitarian" turns out to be less cut off from the world than she thought. First, he lets himself be smitten by Christian missionaries, then his extended family keep popping by, and things turn very horror-like as Takiuchi takes drastic measures to ensure that the man remains the "Solitarian" that she initially identified him as being. The structure of the film is hardly perfect. The young actress who plays Takiuchi as a child is equally effective, if not more so, and the film could have benefited from spending more time on her traumatised childhood, while the horror angle comes extremely late in the piece - something that results in the second half of the film feeling far superior to the first half. Never to mind, Takiuchi never falters throughout and the film is full of neat touches, such as the constant use of upbeat music to highlight her delirious view of the world, smiling as non-Solitarians are hit and assaulted. Takashi Sasano (playing the man she becomes obsessed with) holds his end up very well too, almost becoming just as irrational as her as all the madness spirals towards a close.
