Saw the Odyssey, it was very very good. You might not want to hear this but the message of the movie was very conservative (religious morals are necessary to keep the true nature of man in check, and Odysseus has to atone for his sin in breaking those morals) and the 'controversial' casting decisions made sense in the context of the film: Elliot page's sinon was a character who was a child when he was enlisted into the Trojan war and has experienced the horror of the war which has prematurely aged his appearance (think about those photos of boys who were enlisted into WWI and their gaunt, haunted appearance after the war). It's actually very clever casting. Zendaya's Athena is at the climax of the movie revealed to be taking on the appearance of a temple girl Odysseus saw being executed at the sacking of Troy, with the point being that she is trying to make him remember and come to terms with the mortal sin he committed against her and the gods then. As for Helen, the movie specifically states that her's kidnapping was just an excuse to declare what was actually a political war on Troy and the movie outright says that she's no great beauty with Menalaus himself laughing that idea that her disfigured face could launch a thousand ships.
The only two things I had an issue with was the pacing of the action (which is sort of built into the pacing of the original work so there's not much that can be done about it) and what at some times was stilted writing. Two other things of note was the incredible design of polyphemus and an absolute Oscar worthy performance from John leguizamo
