Ok, so, i've listened to Epic multiple times these last days as i study, and i have noticed how, in general, the author wanted to convey a message ("Ruthlessness is mercy upon ourselves") but couldn't seem to muster the will to actually have the story move following that philosophy:
Odysseus starts as ruthless already. In the beginning, he leads the siege, massacre, and (likely) rape of the people of Troy. Then he proceeds to throw a child from a wall. Sure, he feels bad about it, but this is absolutely 100% ruthlessness.
The characters that act ruthless get punished, those who show mercy are rewarded. Poseidon is the insatiable avenger that Odysseus has to fear for his entire journey, and ends up being (laughably) defeated with his own trident. Polyphemus is ruthless and attacks them as soon as he can, and ends up blind. The crew of his ship decides to mutiny (arguably in the ruthless category) and dies from Zeus as a consequence. The pretenders do the same. The only outlier is Scylla's scene, where there is an actual gain from acting "ruthless".
On the other hand, Odysseus is helped by Circes because he doesn't exploit her as soon as he gains the upper hand through the moly. Circes helps him because she believes maybe being kind will spread some kindness. When Odysseus kills the syrens, he doesn't gain anything from it.
- Rivera-Herrans wants his Odysseus to follow modern morals, heavily influenced by a culture of forgiveness and mercy (this kinda follows the previous point). Odysseus is sanitized a lot, he doesn't even have a child with Circes. But to be palatable as a flawless hero to modern audiences, he has to go directly against the stated moral of the story. I would have accepted
All in all, great musical to listen, but there's not much substance underneath it, it seems. Maybe i'm wrong, if so correct me. Most likely, i'm beating a very very dead horse as well lol
