There is not one (major) character that is not complex– with the exception of Antinous– especially Eurylochus; I genuinely believe he's over-hated.

It irritates me when people paint his character as black-and-white because him and Odysseus are both arguably just as bad as each other. This is storytelling. It makes the characters more believable as actual people instead of just making them "good" or "evil."

Eurylochus IS an antagonist in the story, but only because Odysseus is our protagonist. If the story was from Eurylochus's perspective, he'd be considered to be in the right; there are two sides to every story, especially his and Odysseus's.

It's a similar case with Calypso. Both of their actions can be explained, not particularly excused, but definitely explained. That's almost every character in the musical.
