Talented Joaquin Phoenix and a phenomenal job by Scarlett Johanssen. Near-future AI can fulfill relationship/emotional needs; provide mental wellbeing. A glimpse of a probable future (artificial womb and sexbots or sex-surrogates)? Doesn't push an agenda, just a intricate subject well-explored. Talent does very well and camerawork is great; doesn't draw attention to itself but conveys additional information well.
