Gaspar Noé dials down his typical cinematic spectacle to bring us a slow and moving exploration of dementia and how it drives a loving couple apart. He still has one visual trick up his sleeve, however: Vortex uses splitscreen to show us two lives lived in close proximity but not shared. His cameras follow their subjects individually, sometimes observing them go about separate activities, sometimes occupying almost the same perspective as the characters sit together and engage in conversation, nearly giving us a unified widescreen shot that captures both husband and wife in the same frame – but never being able to. But while Vortex is given structure by its visual design, what it depicts is as crucial as how it depicts it. It’s not a sentimental film, but neither is it harsh – and it’s well worth your time.
