La douleur

The book isn't an easy read, it feels like being trapped into the author's head: this can be a problem because entering another person's subjectivity is always tricky and a source of misunderstanding.

The movie suffers from the same problem and this is why I didn't really like it. The voice over is extremely pervasive (we're bordering audiobook territory here) while nothing, or almost nothing, happens on screen.

In short, watching this movie without having read the book would be a pointless experience imho.
