I’m not sure what film of which you can’t claim specific lenses would color them contrary to their intentions.

I would compare the action scenes in Saving Private Ryan to the “action scenes” of Schindler’s List. It tells you how hard all of this is, how everybody’s confused, how nobody knows what they’re doing, how it’s all a hellhole. I would not describe Schindler’s List as “glorifying” the plight of the Holocaust victims. It tells you how horrid this all is, not that you should be part of it.

(FWIW, Saving Private Ryan and Thin Red Line are often put in the same category of “glorifying the people who fought in WWII”. But in my opinion, “glorify” here means “elicit sympathy for their effectively-forced situation”, and not “glorify”, which I would say is something like La Grande Vadrouille (1966).)

pretty much every war movie

the classics have got Saving Private Ryan, Nolan’s got Dunkirk, Best Cinematography’s got 1917, Ghibli’s got Grave of the Fireflies (released same day as Totoro even)…

for anti-war that’s not depressing, there’s also AFAIK the over-the-top Helldivers

for things that feel “clean” instead of bloody there’s the elegant video game Nier: Automata
