Madman ( 90 minutes) $ 29.95 IT’s with a fond glow that many of us remember early adulthood trips away. Hiking until your feet ached, camping amid the scents of the bush, campfires and, following the ever-shifting dynamics of the adolescent relationship system, awkward fumblings in canvas tents, otherwise known as having a crack’’. A great setting for a film, to be sure. Yet this first effort from director Mark Forstmann stumbles badly, to the point where most of us will recall a far more interesting time in our youth than is managed by the bores depicted here. The plot is simple: five young people set off to find the ancient Wollemi pine in the Blue Mountains, west of Sydney. Then they get lost. The performances, led by Ryan Johnson as Dylan, are terrific and engaging. The problem is the writing. Much is hinted at, almost nothing revealed. Dylan and scatty romantic Pippa ( Ella Scott Lynch) are giggly and lovey-dovey at first, falling behind the others to snog. But when Pippa initiates more of this, Dylan inexplicably turns his head away, refusing her advances. Is her breath just terrible? I’m f--ked up,’’ he barks. Fine, but we need to know why. Die-hard vegetarian Toni ( Billie Rose Pritchard), meanwhile, appears to be in love with Pippa, but again this is delivered in grooming hints and longing glances. Things get a bit grim, and there are many overlong abseiling sequences. And be warned: this film delivers the most frustrating lack of closure since Tim Winton’s The Riders .
