One of the most magnificently crafted anime out there. Imagine the last two episodes of Evangelion spanning throughout a whole anime mini-series, just more thought out and meticulously pieced together.
It's a masterpiece that tells a lot about current society through breathtaking visuals and storytelling. People who say it's pretentious haven't seen the bigger picture of the story. This is a type of story where every single episode can be analyzed frame by frame and in the end there will still be a lot of unanswered questions but, do people really need to know the meaning behind everything?
Some things are just the way they are, and we have come this far knowing this, so I think we'll be fine.
