It never negates the idea.
It never negates the idea that Gordon becomes the next Mayor either. You don't really have anything to support your theory any more than my Mayor idea. The movie does show Gordon soldering on in his job as normal. The final shot of him on the roof of Police HQ, looking through files, and then seeing the new Batsignal really paints the image that he is there for the long haul.
However, gordon's resolution comes in being willing to act and not hide behind a facade as he'd done regarding the Dent act, so yes, it IS irrelevant what happens after that. Both Bruce and Gordon learn their lessons throughout the film.
I don't understand this at all. What do you mean he becomes willing to act? When was he ever unwilling to act against any threats to the city?
What lessons did they learn from the Dent lie being exposed? You still haven't clarified this.
Not necessarily, this is Bruce's and Gordon's story.
In what way is this movie Gordon's story as much as Bruce's? Gordon's smallest role was in this one.
Blake is a reflection of the people of Gotham, and so his response is representative in that sense.
Blake is not a reflection of the people of Gotham. Blake is the conscience voice who is urging Bruce into action as Batman, and telling off Gordon for what he did wrong.
A reaction shot from the crowd, even two regular citizens just to give a flavor of what Gotham felt about their white knight hero being a fraud would have sufficed. The revelation of the Dent lie didn't alter anything.
However, I'm pretty sure people themselves are a bit more preoccupied with being barricaded in their homes because a terrorist has taken their city.
Which again made the revelation of the Dent lie pointless because it didn't change anything or show any reactions to Gotham's people, and had no effect on Bruce or Gordon except Gordon getting a verbal thrashing from Blake.
Everything that happens in terms of the characters realizing they need to face the truth head on happens after this moment.
Really? So list me all the instances where these truth revealing moments happen for all the characters after the Dent lie comes out, please. To me there is clearly only two big truths that come out in this movie:
1. Rachel's letter, and how she chose Harvey Dent over Bruce. That was great because it helped Bruce realize he did not miss out on his only chance at a normal life because he realized Rachel could and did move on and so he could. He could move on with Selina.
2. The Harvey Dent lie which had no repercussions except the Blackgate inmates getting released. Although Batman getting a statue at the end would also be a factor because if they still believed he murdered Dent, their White Knight who gave them 8 years of peace time, and all of those people, too, they would not be raising a statue to him, whether he saved the city or not.
Sure, Gordon already regretted it, but he didn't actually have to face himself for it, he was hiding in the shadows like Bruce.
Gordon was not hiding in the shadows at all. He was out there in public doing his job as always, singing Dent's praises to the public etc. The only thing he was hiding was the truth about Dent.
The revealing of the letter is what for them is the unburdening of a secret that froze them from instilling true change, something they now could no longer stay hidden behind. They had to face the truth that what they'd done was just a temporary fix that wasn't truly what bruce had wanted. He had wanted a Gotham strong enough to keep itself safe. So yes, it matters to them, whether it mattered to the people or not, making it irrelevant to see more of the people's reactions.
The revealing of the letter did not change a thing except unleash a bunch of criminals onto the streets. I've asked you twice already where was Gordon's attitude change towards things once the truth about Dent came out? Before it came out was he against the idea of stopping Bane? No. Was he against the idea of Batman coming back? No. So where is this character change?
Or Bruce's for that matter.
