Charlie Stratton's adaptation of Emile Zola's 1867 novel Thérèse Raquin begins promisingly enough.
It benefits from a lively supporting cast of British actors (among them Matt Lucas in splendid whiskers as a police officer and Shirley Henderson purring away as his good-natured but nosey wife.)
The film-makers recreate 19th-century Paris in detailed, painterly fashion. Jessica Lange is in scene-stealing mode as the matriarch.
The problem is that audiences are likely to become as fed up with the murderous lovers (Oscar Isaac, Elizabeth Olsen) as they become with each other.
