Even if that were the case, the Odyssey is a work of fiction; we don't even know if Homer actually existed, if he was a single person or multiple story tellers blended together by lack of details...

"Critics" pretending to know and be outraged about X not been exactly what they thought when they read the book cliff notes in their mom's sock smelling basement are just noise

It's so weird to be complaining about the accents. It's a movie that takes place in ancient Greece, FFS; we have no idea what their accents would sound like if they were somehow capable of speaking modern English, since their entire culture pre-dates audio recording technology (and modern English, for that matter) by multiple millenia.

Seriously, people are just weirdly conditioned to the classical world speaking with a British accent for some reason, I guess.

even so, who cares? it's not a documentary
