A little surprised about some of the negative comments this little gem has received. Still we all have different tastes and expectations.
Personally I found this a delightful film to participate in - yes nearly everything is 'telegraphed' and the mid-story turn points and ending are highly predictable.
It's a story simply told, well acted and directed. I would even go as far to say that you could watch this film in its native language with little or no knowledge of French and without using subtitles* and understand it all.
* The English translation is particularly good and uses common expression rather than the more formal in keeping with the original dialogue - thus it tends to be more European English than American English.
Like a lot of European films it is filmed as a snapshot of real life - at no time do you have to suspend your belief. The story is simply an amalgam of real documented events.
If you like films crafted as Art then this will probably appeal to you. Switch of the phone, put the kids to bed, open a bottle of red wine and chill-out.
The soundtrack is particularly good and cues the emotions and actions perfectly.
Watch the film to its real end. - Under the end credits.
