The list is intended for people who really value a story that brings them deep reflection. May they take you out of comfort and make you perceive life in a different way. Not all stories bring an obvious reflection, some animes...
"realistic" military animes; meaning as realistic as anime gets anyways.
Arab / Middle-Eastern based anime which has some themes, characters and plots related to the culture and environment, including neighbouring regions.
