It may make look a boomer but my fav is Band of Brothers.
Damn, the amount of work and quality that the producers and directors put in this series is something absurd. This series is a true masterpiece and a must watch title imo.
The episode that the soldiers discover a concentration camp and show the horror in its most naked face, the denialism of the citizens of the neighboring city (German) who did not believe that it happened until they saw with their own eyes and help the soldiers to move the thousands of bodies. If people who were a few kilometers from the camp did not believe and denied the existence of such horror, imagine how easy it is for someone nowadays to simply follow the same attitude and deny all these facts...
well it seems that I get excited talking about this series again, but that's it, band of brothers.
