Shoujo Kakumei Utena
We at GeekNights reviewed Shoujo Kakumei Utena (Revolutionary Girl Utena) many years ago. It's a fantastic, A-level anime that has stood the test of time: something every anime fan should watch at least once.
Utena is a complex show with a complex story, nevermind the imagery, allegory, music, and everything else that makes it a staggeringly difficult work to grok with fullness. Thus, rather than attempt to cram all of that into a single, mind-shattering episode of GeekNights, Rym and Scott have decided to analyse the show, episode-by-episode, for the entirety of its three seasons (39 episodes).
Consider this a sort of "viewer's companion." Nothing will be spoiled at any point beyond what would have been seen if you were following along. Watch each episode after you've seen the relevant episode of Utena.
