I have seen my fair share of animated movies - effortlessly more than 98% of casual viewers. To those who have worked on this movie - if you are reading this - bravo. The story is intriguing. The music spot on. This is obviously a work of passion and homage, but it already feels like one couldn't reliably date it, were it given to someone without telling them when it was produced. This movie will be found and enjoyed by those lucky and inquisitive enough for decades to come!
Going on a tangent: The warring Olympian-Titan myth in this movie is a gem. "The greater the sin, the greater the mercy: the deeper the death and the brighter the rebirth"
And a further side note: Sure, everyone reading this would have seen better animation and have heard a more memorable soundtrack - give me Hans Zimmer and the Ghibli Team and you'd get both. I can think of plenty of movies where the violence (animated or not) is "cool". There's nothing of the sort here.
