I have found essays elsewhere on the interwebs that have lots of juicy analysis of Revolutionary Girl Utena. I will collect links to essays in this post, and replies can focus on specific essays or share links to analysis sites/essays I’m unaware of.
There is a lot of good analysis here by “Jay Scott”
This website is run by The Empty Movement which has been analyzing Utena for 20 years.
