A movie should fulfill it's promise. The script, acting, direction, lighting, and photography are better than most foreign films, and even the sound holds together. Americans (myself included) prefer more closure than the ending provides. And I'm still unsure whether or not I understand the ending. But the truth is that for a Saturday afternoon on a cold winter day, it was beautiful to look at, held attention, better crafted, and far, far, better edited than much higher budget productions. The credits state that it was filmed with 16 people in 16 days and there are some interesting names in the 'Special Thanks' credits that are encouraging, and might explain that success. So IMO the movie fulfills its promise even if the crew didn't carry the story to a comforting end.
