I like the setting of this movie being that it shows Joker's personal life and the daily challenges and struggles that he faced through his job as a clown, caring for his sick mother and having to deal with the rough society. I also like how this movie is full of emotions that also effect the viewers which help feel what the Joker is also feeling, through his sadness, his fears and his anger.
What I also find though is the movie can drag on and seem quite long, I found that all of the scenes were relevant but were carried on quite longer than it needs to be. I feel that it could have gotten straight to the point but the twists were definitely a bonus.
