THE foundation of every narrative film is the screenplay. French director Dominik Moll co-operated with Giles Marchand in writing “Only the Animals”. Which of them devised which moment became irrelevant once the result of their collaboration reached the screen. Is what they contrived with “Only the Animals” worth watching? You bet it is. Why do I have the gall to predict your reaction? Because time, place, motive and behaviour in this economically-populated drama of adultery, murder, criminality and mystery fit together with tantalising precision that begins with a Sierra Leone farmer riding his bike to market carrying a goat on his back and ends with a high-country French farmer foiled but not the loser in an online scam explained in delicate detail.
