Definitely not for everyone as it's (a) incredibly slow and (b) long (2 hours and 13 mins on the DVD I rented and (c) has some story lines that absolutely do not work.
The cinematography is amazing as having been to Beijing, it truly feels like it when they are out and about. That low-level lighting at night just evokes the whole place. The amusement park is classic but it seems half empty. That's the thing, this is a movie that takes place in Beijing, a city of millions, yet where are the people? The relationships--some work, some don't--but what gets me is some people who try to portray this movie as some sort of comment on globalization. All I see is what has been going on for centuries in most Third World countries--people from the countryside move to the big cities to find a better life. Some do, some don't.
The whole movie seems more like a documentary look into people's lives and that is a credit to the acting.
But really, if you haven't been to Asia, I can't really see this being worthwhile renting because it moves at a snail's pace and seems intended for those who love to read meaning into everything. All I got out of it was--wow, why didn't I go check out this place called The World when I was in Beijing. It's even more bizarre than Huis Ten Bosch or Canadaland or the other weird Western land ripoff amusement parks I visited in Japan.
