Gannon Nordberg’s review published on Letterboxd:
Joaquin Phoenix transformation into Arthur is incredible — certainly on par with Christian Bale’s in ‘The Machinist’.
It’s very disturbing.
The music and score is very scratchy and unnerving.
I’m sure this was also intentional, but there isn’t a well lit scene in the whole movie. Everything in Gotham city is dark, dirty, and threatening.
As the movie progressed, things got darker and darker (thematically) all the way through the climax and closing of the film.
