What are some pieces of fiction with the best mythology?

I don't mean real world mythology. It can be anything. Movies, shows, books, and games.

Here's the stuff I have watched/played/read:

Baldurs gate 3

Clair obscur: expedition 33

Skyrim/oblivion

Lord of the rings trilogy

Star wars

Attack on titan

Black clover

Avatar the last airbender/the legend of Korra

Wizard of Oz

Narnia series

(These are some I've seen based on real world mythology)

Crouching tiger hidden dragon

Natsume book of friends

Jentry chau vs the underworld
