Joker: Smile mix with the red

  October 12, 2019    

The one who creates good or bad inside a person is his environment. If one wishes to be good, his environment intrepret in his case. The work of infamous persons will get praised. The one who without consideration will become clowns. How will you react to the society which make fun of us? Answer to that question is the Joker!

Cleaning peoples of the Gotham city are in strike for their righteous wages for days. Rules are just ignorant to them. Because of this waste has increased enormously in the city. Poverty, struggles and war makes all the stores get closed. The director shows the real face of capitalists through this movie.

] "I used to think that my life was a tragedy , but now I realize, its a comedy" by these words Joker/Arthur starts his character on the movie.
