This is the third time I'm rewatching the Hades series, and for the third time, I feel like it could have given more. Don't get me wrong, Sanctuary and Inferno were fun to watch and it had the classic Saint Seiya's vibes, but Inferno especially, was rushed (so was Elysium, but we don't talk about that). The setting of a Dante's underworld was very intriguing, but a lot was left unexplored, like all the Prisons. 12 episodes weren't enough to do so after all. But despite the rushed product, I loved the art style, the Kanon's redemption arc, and the interactions between some characters (especially onthe last episode). Keeping the music of the original serie was a nice touch and made it feel even more nostalgic.
It has some flaws (which anime doesn't have at least one?), but I would recommend this and Sanctuary to people who haven't watched the series yet.
