The film has a strong ending, but I had trouble getting into it in the beginning. This might also have to do with the lead role - she was too much a victim I thought. After a long while I could start to understand her struggle with her "real" life.
What I really liked was how the back and forth transitions between her memories and her present situation worked. It seemed there weren't too much and not too few. And the ending with her husband welcoming her "home" was quite impressive.
There are some really amazing shots of trains arriving in the station, especially at the beginning and just before the end.
