Culture clash in modern-day Australia, as a 19-year-old Greek named Ari, handsome but feckless--and prone to snorting and shooting drugs--rebels against his hot-tempered papa, a man of values and culture but perhaps stuck in the past. Ari's inner-anger is all-encompassing; he lashes out at his family, at his diverse neighborhood (which appears to be an otherwise peaceful agglomeration of working-class Asians and middle easterners) and at girls who find him attractive. Ari's father is shown as disappointed with his wife and children, but even in the flashbacks there aren't any clues as to what would've made this man happy (he and his wife protested for Greek rights, but does he want his son to continue this fight--and what would the fight be about, the same issues the father fought for?). As Ari, Alex Dimitriades struts and preens like the next John Travolta (in fact, some of the home front squabbles, particularly one around the table, seem lifted from "Saturday Night Fever"). It's a risky role for the actor, who must keep up a perpetually ill-mannered demeanor, complete with lusty, angry homosexual activities which Ari keeps secret (his father hates 'poofters'); yet, Dimitriades, self-enamored and intense, makes the part work for himself and the audience. He's helped a great deal by director Ana Kokkinos, who also co-adapted the screenplay from Christos Tsiolkas's novel "Loaded" with Andrew Bovell and Mira Robertson. Kokkinos keeps the camera busy and free-flowing, although she stumbles when attempting artiness, which in this case is akin to dreariness. Some marvelous moments emerge in what could have been just another coming-of-age melodrama. **1/2 from ****
