The film very much, with meaning. Mariyon Cotillard played excellent, the music of Edith Piaf in the film probably is not accidental, it was Cotillard played the role of Edith in the biopic "Life in pink.
On the end of the film among our friends, a hot debate.
At first glance it seems that the main character jumped out, it was necessary to look at Yulu /totem: if she whirled and fell, then it was a reality, if not, then - a dream. While his children looked like in a dream, that pushes the idea that's still not jumped.
And one more thing. We showed how he woke up in the plane and all the participants woke up, too, and we proved it through his eyes, and not as it saw the rest. Hence the question: how the other members out of the first sleep, when the car fell off a bridge into a river. They came ashore, but we have not shown how they woke up.
In general, the film for reasoning about the nature of sleep, that relno and what does not.
