I went to see the movie with my kids last night, and liked it a lot less than I expected to.
My main gripe was the set up of how the city was held to ransom for an extended period of time, which simply didn't feel credible. We have a situation where the bad guys manage to hold a city of ~12 million people hostage for a period of about 6 months (not completely sure of the numbers here) by threatening to blow them up with the fusion reactor. The bad guys keep control by their initial army of outlaws who have been training in the city's sewers, augmented by the hundreds liberated from the Bastille - sorry, the prison. During this time no one is allowed to escape because of the threat to blow the nuke, a threat which is enforced from the outside, yet somehow the city manages to function after a fashion - food supplies are provided from the outside, and somehow enough order is maintained that the city doesn't simply collapse. I would expect plagues and famine and riots, not to mention fire after all the explosions at the start of the siege.
I found this all rather hard to buy. In terms of the story the extended siege is done to give Bruce Wayne time to heal up in his remote prison, and to make his spiritual journey that allows him to escape from it and return to Gotham. I find it hard to believe that such a siege with so many hostages could be maintained - this is a city after all, and would leak people like a sieve. Similarly, the maintenance of order would be a real problem in such circumstances. Least credible of all, I could not swallow that a thousand or so police offices could be trapped underground for six months, somehow supplied with food & such, then be busted out and run off to battle, fully fit and wearing clean uniforms. Really?
Did anyone else spot all the French Revolution/Tale of Two Cites references? I mean the conflict between aristocracy and underclass, the storming of the prison (the Bastille), the citizens' court against the oppressors, the final sacrifice and Bruce Wayne's epitaph, read from the close of Dickens' A Tale of Two Cities. Interesting to see that put into a modern setting.
I wondered about some of the technology also. I thought the helicopter thing was pretty neat, though it was fortunate that the missiles fired at it were so slow that the copter could keep ahead while it outmanoeuvred them . Did Bane buy them from the lowest bidder, perhaps? I didn't really buy that the fusion core could be (a) so easily turned into a bomb, or (b) be removable from the reactor and still remain deadly without the need to keep it fuelled or maintained.
That said, there was a lot to like. I don't think I'll be in a hurry to watch this one again, though - unlike the first two movies in the series.
