We're currently in a golden age of animation, and right now, there's an excellent Prime Day deal available for one of the most acclaimed animated series ever. The Legend of Korra, a follow-up to Avatar: The Last Airbender, is on sale, offering the complete saga for just $57 (usually $98) in this Blu-ray box set. This amounts to approximately 20 hours of content spread over several seasons, providing a substantial story to enjoy in high-definition clarity. Initially planned for a single season, The Legend of Korra became a critical success upon its debut and was subsequently expanded with three additional seasons to further develop the story of the new Avatar. Similar to its predecessor, the show follows the journey of a new Avatar tasked with preserving peace between the human and spirit realms, as she alone can wield all four elements at once. Set in the bustling Republic City, a hub of fire-, air-, earth-, and water-bending cultures, the series depicts Korra's battles against nefarious forces, her exploration of her past lives, and her mastery of her Avatar abilities. Animated by Studio Mir, the show boasts remarkable action sequences and breathtaking locations, with a surprisingly mature and dark narrative for an animated series. The special features include several featurettes, audio commentary tracks, and each season disc is housed in a striking steelbook case.

If you're interested in delving deeper into the lore, the complete Avatar: The Last Airbender series is also available for $21 on Blu-ray. Alternatively, you can purchase both series in their entirety for $26.50, though you won't receive the collector's steelbook cases. In other Blu-ray deals, the Castlevania series, definitely not for kids, is at its best prices yet—including the recently released first season of Castlevania: Nocturne—you can save significantly on the Indiana Jones movies, and the Picard Collection offers a wealth of Star Trek content for just $148.
