David Cronenberg directs Vincent Cassel, Diane Kruger and Guy Pearce in this erotic thriller where a widowed tech millionaire has created an app where he can watch in detail his wife’s corpse decompose within her tomb.

There is a spectacular sex scene. And before that a shocking one. This is on the whole Cronenberg’s best since A History Of Violence. The through line satire about a life lived on apps has a real “I told you so” energy to it. Let down only, but almost fatally, by an interminable final half hour. Every mystery has been resolved. We understand the themes of moving on from grief and sexual desire in sickness as much as health. So why drag it out with the same old impenetrable techno conspiracy that Cronenberg has been dangling like an obtuse prankster in front of us since the Eighties?
