This is, famously, Steven Spielberg's ( Catch Me If You Can ) first film, originally made for TV and later released theatrically, and what it is is really his first monster film, that menacing truck a forerunner of the T. rex in the sideview , of the shark eating Robert Shaw, maybe mostly of E.T.'s pursuer with all the keys on his belt: a creepy, inexplicably motiveless hazard (or at least apparently so to the pursed), one to be avoided at all costs, because you know nothing good will come of a meeting.
Scrutiny, in fact, is the last thing his films can withstand--something that early escapist fare from Spielberg like Jaws, Raiders of the Lost Ark, all the way back to Duel, understood.
His 1970s films were largely set in the present, from Duel through Jaws to Close Encounters of the Third Kind, but then he took off in time and has rarely returned.
The movie, for all its location shifts and elaborate scams, is essentially a feature-length chase, which puts it in the league of early single-minded Spielberg entries like Duel and especially The Sugarland Express.
Spielberg's told enough stories of hopelessly broken homes (Close Encounters, The Color Purple), guys proving their worth (Duel, Schindler's List), and innocents making their way in a corrupt adult world (E.T., Empire of the Sun).
That it's a chase picture is only another of the film's many plusses – from Duel to Jaws to Minority Report Spielberg has shown time and again his rapturous love of the chase, and when he's on top of his game, as he is here, precious few do it better.
