The movie set out to give this feeling and succeeded. Also the joker theme with the violin mixed with the drum music and the rythm of the whole thing is perfect for this type of character.
Also the perpetual movement he starts with inspiring the city into chaos almost inadvertently and how it inspires him to keep going felt very natural for his descent into madness.
This is a film I’m glad I saw because it is well acted, written, and directed. That being said I will probably only watch it once.
