I’m probably biased against it cause it didn’t click for me when I watched it, but I don’t think it holds up. It does seem to kinda set in motion the emotional angst that many other anime followed later on and started the trend of “everything is actually symbolism for God and what is the meaning of ‘humanity’”, but I’m not sure either of those tropes were ever really handled well in anime (full metal alchemist, Tri-Gun, etc. for example all get a little heavy handed by the end).

That being said, you won’t waste your time watching it. It is a complete and thought provoking story and is referenced in a lot of pop culture. It just might not be your favorite show.
