If you enjoy all around good slow developing stories and good acting, this is for you, but..
if you need neat and tidy films with everything clearly spelled out and tied nicely up with a bow at the end, then this is probably not for you.
I think this is one of those films defined by the country one is most familiar with. Years ago I read a claim that when something like many foreign (to the US) films are about people while US films are about the story. In many ways, I agree with this and I think this film is a good example of that especially when one reads some of the comments here.
We Americans seem to want neat and clear endings to our movies more so than others that sort of see stories in films as just a segment in a person's life and how a life doesn't necessarily end when the credits roll.
