Kitchen Stories focuses on the life of a single reclusive Norwegian farmer living in the 50s, and how he deals with the constant but incommunicative presence of a bland observer sent to live in his kitchen by a home-science company. (Here's a picture of the ridiculous situation) The company hopes that this observer, and many more spread out across Norway, will stumble upon the hidden habits of single men - habits that will help them build a better kitchen.
And that is the link to PR, dear reader. How many times have you stood behind a two-way mirror, muching on a muffin, critcising the responses of focus group participants? As director Bent Hamer (doesn't that sound like a porn name?) slowly reveals (too slowly, according to some reviewers), the observer's constant but irrational presence inevitably has an effect upon the farmer - prompting the man to change his routine and his habits, to the point where he no longer cooks in the kitchen.
Inevitably, the farmer eventually has a similar effect upon the observer, and the supposedly scientific experiment breaks down as a friendship of sorts develops.
The expectedly pretentious National Post points out that this is a manifestation of a corollary to Heisenberg's uncertainty principle - that the observer of a system must invariably affect that system. Or, as exit poll takers would tell you, people sometimes just don't want to tell the whole truth, and nothing but the truth.
