So the photography is beautiful, as you can see. The soundtrack also gives some great ambience at times.
The point of the film is Arthur Fleck embracing violence. There is a "class warfare" dimension with Gotham falling apart and a movement against the rich, who are probably portrayed too much as a caricature, see the last picture in >>33996, I don't think America's upper class all dressed like that in the 80s. But that's not what motivates the protagonist or determines his choice of victims. It's more about violence as his personal reaction to those who belittle him, but that doesn't explain everything; it's also applied to those who try to tell him what is and isn't funny from a moral high ground. To him, his violence is funny and comedic. It's not a violence directed against everyone, though, he does spare someone who didn't belittle him nor try to tell him what was right.
