The business of the film is to show Tilly trying to find out what that thing was and exacting revenge on everyone, in particular Beulah Harridiene (Fox), the shrewish spinster schoolteacher, who conspired against her.
Adapting Rosalie Ham's 2000 novel, Moorhouse and Hogan have created a series of moving cinematic tableaux which are often eye-poppingly striking, but it's an annoying film to watch because no scene gets the chance to breathe before we're dragged away from it.
Tonally, it makes for a hell of a mess: there's a duel between seamstresses and a long lead-up to what looks like a screechingly unlikely happy-ever-after ending involving the hunky Hemsworth but the film, which is too long by at least 20 minutes, has much more in store as skeletons tumble out of pretty much every closet in town.
It's full of pleasurable aspects: David Hirschfelder's busy score is a treat; Weaving as a cross-dressing cop has a good time and, as a result, so do we; and Winslet nails the upper-crust Aussie accent dead centre.
But she's miscast, really, and not just because she's too old for the chronology to add up.
A femme this fatale needs to have an air of mystery about her, but Winslet shows us too much, literally and emotionally. Like the film, she's full of big gestures, but never manages a grand one.
