I don't know who wrote these shows, but they should have researched the mythology before writing it. I've seen other instances of them getting it wrong, but this one was ridiculous. You cannot descend into Hades, Hades is the god of the underworld. You can descend into the underworld. The writers should definitely have done a lot more research. And Persephone is the wife of Hades. She is only allowed to spend some of her time there, but she is forced to return to her mother at Mount Olympus. And Zeus didn't cast the box into Hades, his brother, he cast it into the underworld.
