I finally watched All Quiet On The Western Front which was brutal and fantastic but it strikes me that I don’t know as much as I would like about this conflict.
What are some good sources for analysis and historical perspectives?
Edit: thank you all for your recommendations and perspectives 
Storm of Steel the memoirs of Ernst Junger are very highly recommended. I never got around to buying a copy but I have had it recommended so many times. The guy became a Nazi then turned on them but not for a grand moral reason so much as they killed his son. However his contradictory pov that has been described as both glorifying war and anti-war, and his being a young man who was exactly the Prussian archetype make him a perfect case-study. The Russian wikipedia article gives some good analysis if you want https://ru.wikipedia.org/wiki/%D0%92_%D1%81%D1%82%D0%B0%D0%BB%D1%8C%D0%BD%D1%8B%D1%85_%D0%B3%D1%80%D0%BE%D0%B7%D0%B0%D1%85 https://politosophia.org/page/ernst-yunger-v-stalnyh-grozah-mirovoy-voyny.html https://www.amazon.com/dp/0143108255/?coliid=I178UE3BU40311&colid=1JEGNQDCXXPVB&psc=1&ref_=list_c_wl_lv_ov_lig_dp_it
Good article on the mindset of that general and honor https://encyclopedia.1914-1918-online.net/article/wartime_emotions_honour_shame_and_the_ecstasy_of_sacrifice
Origins and meaning of WWI is a brief anarchist rundown of a lot of that officer mindset and what we should take away from the war https://theanarchistlibrary.org/library/john-zerzan-elements-of-refusal#toc12
For an in depth critical view of WW1 and why it happened Mccullough's work seems interesting https://www.amazon.com/How-First-World-War-Began/dp/1551641402
This whole reading list is leftist and seems amazing
