...so including female characters in WW2. And battlefield has never been historically accurate. I didn't the gaming community being up in arms about wide spread submachine guns or the fact that A7Vs kept spawning in BF1 nor do I see anybody complaining reflex optics being in the BFV footage. Both of those issues are historically inaccurate and "inauthentic"
The underdeveloped and desaturated visuals of the movie were emulating the limitations of film in the 40s. Insitu documentaries were shot, edited, and distributed as war propaganda but still fell into that visual look. Everything since Private Ryan has sought to emulate Private Ryan. If you watch pre-Private Ryan movies and documentaries, they don't have the "authentic feeling" you're talking about. Frankly "authentic feeling" doesn't mean shit and a videogame is not wiping away history.
