Halfway in the movie I kept telling myself - this is just a movie.
Yes- I was entertained with all the gizmo - but the overpowering story here is about the inherent Evil of Batman's opponent (The Joker) who is not swayed by Money but rather is swayed by his ability to create Total Chaos and Fear in the lives of the innocent.
What did I take away from the movie? The Good has to fight Evil in order for Evil to be defeated. Evil will not walk away because of speeches and slogans.
