Tau: Julia (Maika Monroe) a grifter and petty thieve is kidnapped from her flat and wakes up in a house of horrors. It is the den of mad computer scientist Alex (Ed Skrein). The building is controlled by an AI, Tau (voiced by Gary Oldman). Along with her co-captives Julia has an implant which records her reactions to various tests and stresses. The only way to escape from Alex may be to form a relationship with Tau. This is Federico D'Alessandro's debut as director and while not a classic neither is it the disaster some critics allege. While Skein is a rather camp stage villain (anyone who tortures an AI would kill kittens), Monroe puts in a convincing performance as she battles killer robots and sweet talks Tau, in the early stages of the film she even manages to cause an explosion, this is one streetwise grifter . And a nasty robot it is, impaling escaping test subjects, inflicting pain, makes Bender look angelic. Tau also has a fleet of mini-drones to clean up and monitor the captives. Some pretty well framed shots especially in confined spaces when the robot pursues Maika and returns her to captivity. Mainly shot in the "smart" house the film seems to drag at times, this is in part due to a script which fails to provide background details- eg Julia's apparent military training. Gary Oldman is rather wasted as the voice of Tau who is not the most convincing AI in SF cinematic history. 6/10. On Netflix.
