I think EVERY mum feels like this at some point. I know I felt let there had to be more to me than just a mum. Life does get small, boring routine when you have a child(ten). It's just not everyone can afford to make a choice like that. A single mum can't just walk out on her life. Maybe change the title to "The Daydream of Escape"
By the time she's in the park in Paris, I actually felt angry that she could be so selfish.
All in all this film shows a woman who runs away in a fantasy, tries to forget who she was only to have a giant slap of reality across her face.
