A Joker origin story - or one man's descent into madness?

Rating: 8/10 (17 October 2019)

Brilliant narration around a superb oscar-nom worthy performance from the everembrassing Joaquin Phoenix.
Only real issue I have is when a major origin story of a beloved(?) character only takes around 10 days to complet; leaves me lacking more background.
Other than that, an utter disturbingly excellent and buzzkiller piece of American cinema.
