It's clear Grant is out of his element and wishes to remain so, but his condescendence is not only noted, but slyly, and nonverbally, remarked upon by hotelier Charlie (John Meillon, "Crocodile Dundee"), anticipating what will happen down the tracks.
As a child I definitely preferred the New York material, since it moved faster and was instantly relatable (if only to other media representations of NYC), but in retrospect these are minor virtues compared to the melancholy beauty of the Australia portion, which as a bonus has obvious roots in the national cinema--with references to Walkabout, Wake in Fright, and other seminal works of Ozploitation--that offer something extra for the student of film. 2 That said, the rousing climax, a variation on the old airport confession of love, sends the picture--and us--out on a high note with an affirmation of the essential New York character (brotherly, romantic), as a crowded subway station pulls together to help Sue 3 confess her love for Mick.
