Perhaps what was most interesting about Bane was that, whilst his real agenda was a scorched-earth anarcho-primitivism of the same brand (albeit with better execution) than Ra's al-Ghul, his cover was the kind of pre-Marxist revolutionary left-wing ideology last seen during the days of Robespierre. Given the storming of the prison and the fact that Bane also gets it in the end, I'd be surprised if this is an accidental reference.
Talia al-Ghul seemed to go the other route, of techno-environmentalism combined with (no doubt) the standard centre-right idea of economics, before also revealing herself as, well, Ra's al-Ghul's daughter.
The science around the bomb/reactor was arguably dubious, although we are never told how it works. It seems, though, that the film is not merely post-Lehman, but also post-Fukushima, given this aspect of the film.
I'm no expert with nuclear weapons, but wouldn't there be an
inferred holocaust from the fallout of the bomb? At least some people in Gotham would die, wouldn't they?
The other thing is I've already encountered the stupid, 2D analysis of it as some neocon flick (thanks,
Guardian, for ridiculously oversimplifying things - they seem to be on a dumb streak lately), completely ignoring the fact that Bruce Wayne loses (gives up?) his house, his business and winds up presumed dead, instead opting to sit in a cafe with Catwoman than restore his wealth.
