Extremely well-acted, well-written, well-shot art-house dramatization of one of the most ridiculous ideas that might have been dreamt up by a third grader. The preposterousness of the idea and the theory behind the science coupled with the utter seriousness of the production makes it a very weird experience, producing some ill-timed laughter and making it very difficult to get into the movie. It's not the fault of the actors, who do what they can. And some of the camera work and visual imagery is interesting if not completely relevant to the story. Unfortunately, the overall effect is an unfortunate pretentiousness that negates any message or metaphor that might have been intended.
