I watched this with my son yesterday. Before (and after) the film, we disagreed about Helen of Sparta being black. Watching the film, my views on this are unchanged. Actually that is wrong, they are different but I will discuss that later.
Unlike Elon Musk I loved the film. But then I have watched it, something he may not have done. My son liked it, but felt that certain bits who not have been removed, but the film is already three hours long. The only way to include all of his voyage is to make it into more than one film, and we saw how true adaptations like that were to the original story with Lord of the Rings and The Hobbit trilogy’s. I had a translation of The Iliad many years ago, when I was a teenager, but I only ever read adaptations of The Odyssey, and watched the cartoon (which I loved). If you like other Christopher Nolan films, you will probably like this.
As for diversity, I do think it is important in films, but there are ways of adding it. The Percy Jackson TV series has Zeus as black. Athena is portrayed by Zendaya, someone who is not white. If I was to cast the film to be diverse, Helen of Troy but not her half sister Clytemnestra would have been mixed-race. You can argue that both could be black, both, with other siblings, being hatched from an egg. I would have had Circe, Calypso and Athena reflecting diversity. But that would have still annoyed many. If someone is to be annoyed with the film, it should be for the same reasons as my son, that being what they left out, or other matters that were changed. Odysseus left Troy with more than three ships, his being the only one to survive with the Laestrygonians. There are so many other parts of the tale that have been changed, Circe seducing Odysseus for a year being another example. And Elliot Page was great in the film. I am surprised that those on the right were not in uproar about his inclusion, but I am suspended from Twitter and cannot be arsed to appeal it.
Basically if you are racist, don’t watch it. If you want a tale true to the original story, don’t watch it (which is why my wife stopped watching The Hobbit films).Otherwise it is an enjoyable “male” film and I would consider watching it again.
