This one goes straight for the box of stuff your parents threw out while you were at school. Production I.G built an entire world out of the junk you stopped loving, and Oblivion Island is stacked with it: teddy bears, model kits, picture books, a shining rock from the park, all hoarded by fox creatures who slip through a shrine torii to raid our forgetting. Haruka goes in after her mother's hand mirror, gets Teo as a reluctant guide, and the Baron sits at the top of it all like a landlord of everybody's abandoned childhood. Yes, the plot is thin, and yes, there are stretches where the 2009 CG is clearly showing off what it can do. But the showing off is gorgeous, and the premise earns it. You will walk out thinking about one specific object you can no longer find.
Haruka is a 16-year-old whose mother died when she was very young. She has been raised by her father, a workaholic who is rarely around, and home has come to feel lonely. One day at a shrine she spots Teo, a strange fox-like creature holding a toy plane, and chases after him. She ends up on Oblivion Island, a fairy-tale city built by beings from another dimension who slip into the human world unseen and carry off the treasures people forget as they grow up. Among the island's collected keepsakes, Haruka comes across memories of her own childhood. Humans are not meant to be there, though, and the Baron who rules the place turns his attention to the intruder. The film is a fantasy adventure about whether Haruka can recover and make peace with what she has lost.
