I see that there are a few "The Handmaid's Tale" questions on this site.
I have only seen the TV-series, not read the book, and I may recall incorrectly, but i am not aware of any supernatural/fantasy elements in the series. Nor do I remember anything not readily explained by current real-world technology.
Granted, the world the story is set in is rather bizarre, but I am not sure if it has any straight up fantasy or science fiction elements?
Correct me if I am wrong, I may remember incorrectly.
