I think the fact that retellings of Greek Mythology are getting more popular is amazing, and I hope it inspires more adaptions of less well-known myths, because, frankly, I'm getting sick of the same three or four myths being used as representations of all Greek mythography
In the meantime, if you're looking for a good musical adaptation of the Iliad, allow me to direct you to the frankly underappreciated play - Aristos : The Musical
If you liked TSOA, you'll love it
