The plot of Speak No Evil is an exploration of what can happen when someone driven by a cultural urge to be polite and avoid any form of confrontation, encounters a psychopath who exploits their very nature. Speak No Evil is a very European psychological horror and I stress that point because this film will not necessarily play well to audiences who are not so familiar with such institutionalised deference or passivity. Danish writer and director Christian Tafdrup skilfully and slowly builds the tension, but the plot contrivances of the final act do somewhat mitigate its credibility. Hence realism gives way purely to threat and suspense. If you’re the sort of viewer who can countenance that different cultures, age groups and political leanings can dramatically impact upon one’s behaviour, then you may well get through Speak No Evil. If you struggle to come to terms with the poor decisions made in an episode of Scooby Doo then Speak No Evil will leave you screaming at your TV.
