'Possum' (2017) – Matthew Holness.

A truly unique vision of psychological horror, Matthew Holness's distressingly downbeat 'Possum' is a fascinating, consistently unsettling exercise in painfully prolonged disquiet. Exquisitely eerie, this detailed, ruthlessly grim, morbidly crepuscular descent into the dismal depths of a horribly tormented mind is not readily forgotten! For all its suppurating griminess, 'Possum' is demonstratively one of the more strangely beguiling nightmares I can ever recall seeing, drawing you uncomfortably deeply inside its malign mysteries like a black hole. With Lynchian deftness, director Holness manifests a sinister suburban milieu that is both stiflingly prosaic, and disturbingly deranged! I have little doubt that mucky misanthrope Uncle Maurice's diabolically dingy digits are sure to leave an indelible impression on horror fans for many years to come!
