This is a mixed film, definitely very disappointing after the synopsis looked promising - the sad thing is that it's very easy to see how it could have been done better. Much of the acting is, as others have remarked, nothing less than dire; the directing verges on the pretentious and the screenplay is at times predictable and irritating. I'd have liked to see it done by a larger, perhaps UK company - the plot would transfer very well to a British setting. Good actors, better structure and generally higher quality would have enabled a worthwhile film to have been made from what is a reasonably promising idea.
On the positive side, the film has some excellent music (notwithstanding that "down by the riverside" itself doesn't have the same impact as, say, Puccini's "Butterfly" does in Peter Jackson's "Heavenly Creatures"). There are some gloriously surreal elements, particularly involving the driver. Despite its faults, still a film worth watching, but oh such a disappointment in the end.
