The movie actually discussed two questions besides the war of the good and the evil

Rating: 9/10 (12 September 2012)

As the Batman sequel which happened 8 years later in the story, the movie discussed two questions besides the war between the good and the evil:
First, what kind of evil was the worst evil? In the last part, the Joker challenged the dark and evil side of human nature, and in this movie, the villain not only continued to challenge the dark side of human nature, but also did it in a sounding name: the people. The evil masked by justice is the worst evil.
For the Chinese people, the speech by Bane in front of the city hall was entirely a replica of the inciting speech in China's 1966-1976 Cultural Revolution, which was one of the characteristics of that era with black and white reversed and justice ruled by evil. So it was a little weird that this movie could be shown publicly in Mainland China.
The second question was which to trust, people or institution? Apparently, Batman had always been committed to find "a good guy" to entrust him the business of justice safely. However, it was clear he failed. Miranda, his heir, even slept with him, but was still the bad guy. This was not accidental, it indicated that you should not put all hopes on a single person, even if he turned out to be a good man, as there was no guarantee that he would not deteriorate or make something evil in the name of justice, intentionally or not. Therefore, we should trust institutions rather than people. At this point, the movie was an obverse to hero movies.
Last but not least, this movie seemed more like "Rise of Robin" rather than a story focusing on the Batman, or a story on "how the Batman retired and handed his career to Robin".
