Derrière les murs

The French film titled Derriere les murs (Behind the Walls - 2011), lasting 1h 30 min, focuses on a writer who isolates herself on a rural property to write a book. The beginning of the film arouses curiosity and becomes quite obvious that the film had a careful investment in the scenery, with excellent costumes, photography and lighting, in addition to a small group of good actors. The story starts well, but as the film progresses, it ends up getting lost, to the point that it is up to those who watched it until the end, the decision to infer what really happened. In my opinion, from a certain point in the film, the excess of the medicine taken by the writer, which caused hallucinations, ends up participating in the cast.
