The French seem to have a talent for making a completely believable sense of time and place in films. And characters. A lot of French movies feel less like standard films than time capsules perfectly preserved. It is so easy to believe what you're seeing is real, or that what you're watching actually happened.
These movies, perhaps as a corollary, often leave much semblance of plot behind in the pursuit of realism, and that's fine. It makes a welcome change from plot-driven Hollywood films.
However, this can be an issue at times, such as when a movie needs a resolution. "C'est La Vie" is an example. The movie feels so real that a climax seems overtly stagey anyway, but here it's also surprisingly depressing. And it seems to come out of nowhere. The depressing ending isn't foreshadowed at all, so it's a slap in the face, and almost made me angry.
I enjoyed the movie for most of it, though. It's about two girls, twelve and eight, who go away for a holiday to the seaside in 1958. The older girl has a puppy-love romance develop with a boy, while cracks become more apparent in their parents' relationship.
The parents didn't evince much sympathy from me. I wish the focus had been on the kids more. Possibly, then, seeing the failure of their parents' relationship through their eyes, would have prepared us for the conclusion, making the ending sad and poignant rather than depressing and bewildering.
