I saw this movie at the Heartland Film Festival last year here in Indy, and I though it was probably one of the best movies I saw last year. Even if it wasn't, it was certainly the most original and different I've seen in quite a long time.
It is the story of Amy a young girl who has been mysteriously deaf-mute for several years, for no medical reason. She lives with her protective mother, played by Rachel Griffiths, who tries, with no avail, to understand her daughter's condition.
Most of the plot involves their move to small alley in a downtown Australian town, which is populated with all sorts of different, funny characters. The film goes along with just the right pacing---it doesn't rush or lag, just goes along, much like its characters, who aren't entirely sure of where their lives are going, but go on anyways.
This film blends tragedy, comedy, drama, and fantasy without every confining itself to one genre. It creates its own world, using nothing but a subtle script and incredible acting.
One more comment: I thought that the scene involving the little girl and the little guy, and his drumset had to be one of the cutest scenes I've seen in over a decade.
