okay, to answer in pictures.

do you have the same problem with this? I think you're missing how much reportage
always becomes incorporated in art. Do you think the stormtrooper gathering in the Star Wars movies would look the way they do if not for referencing WW2 newsreel footage of Nazi troopers? Do you take the same issue with this?
The Jewel of the Nile directly references the Nurembourg rally in it's finale - is this as bad*?
I understand how you're getting at direct homage, as opposed to suggestion - yes, those videos posted above are very similar - but where you see exploitation I see the beginnings of cinema getting to grips with what happened. This is how things are parcelled so folk can move on and they become scars rather than a fresh wound. See
A Night To Remember for example.
But yeah, you may as well complain that the destruction of the blimps at the beginning of
The League of Extrordinary Gentlemen is too close to archival footage of the Hindenberg explosion. What, in the storytelling capacity is actually lost by that? What you aren't convincing me is that the shot above somehow cheapens the film - i'd far more say that it gives it a resonance.
if you want to look at it as exploitation, at worst the message is “New Yorkers will try and try and try to overcome” which certainly doesn't make jokes at the expense of the Trade Centre victims. That a film of this kind can exist now, with vague satirical nods towards governmental procedure following a disaster in THAT city, featuring photo-realistic destruction that ivokes images of 9/11 is testament to a continuing freedom of the arts in corporate American film making. which is IMPORTANT and hugely encouraging.
*i am loathe to use the Nazi example here, but I feel these are films everyone is likely to at least have some knowledge of.
