I really enjoyed the first two seasons of The Magicians. Chaim Gartenberg writing for The Verge explains better than I why you should watch season three (after watching seasons one and two, of course).
Unlike the whitewashed worlds created by Rowling and C.S. Lewis, the characters in The Magicians are a diverse cast of actors portraying characters with a wide range of sexual preferences. They feel like real people with real problems, from relationship drama to more serious issues like trauma and sexual assault.
Yup. Plus, so much more.
