That said, there's a vein of criticism in the film aimed against those types of journalists who are motivated by getting a scoop more than by upholding any sort of principles.
Somewhat ironic given the one journalist the film thanks is entirely unprincipled, and two of the people they took footage from are literally provocateurs who try to make themselves into the story, or create the story. I don't think it's a particularly good message, either, because journalists "getting the scoop" isn't really a problem these days. On the direct contrary, journalists studiously
ignoring the scoop because it doesn't play well, and instead merely repeating the "party line" whatever that is, seems like more of a real issue (especially as that party line is moving rapidly in a specific direction thanks to the Overton Window).
I think the most resonant line for me was Kirsten Dunst's character saying she was a war journalist overseas because she thought it would make Americans back home see the horror so they'd know better than to let it happen here. The implication being that no, it didn't actually work.
Who's to blame for that?
I mean, I don't know what the film is saying here, but the degree to which war journalism is censored today (in the US and UK mainstream media - hate to use the term but it's appropriate here), is insane, compared to how it was in the 1990s and earlier. I think that contributes significantly to making it in effective for this purpose. Horrific scenes that you might routinely see in the 1990s are now frequently just not shown, or shown very briefly with heavy blurring. The footage is still being shot - it's still making it to the internet (albeit often by citizens not "official" journalists) - you can find it easily enough but is it on CNN, Fox, or for that matter the BBC, in the same way it was in say, 1992? No. It isn't.
So I am unconvinced that war journalism can have much of an impact on people's willingness to go to war, when so little of it really shows the
actual results, and instead a lot of it borders on glorification.
