composed the music for the series. "It’s an orchestral, adventure score, but we wove in a lot of Western elements. There are acoustic guitars, some vocals, the fiddle, and trumpet. Our approach to this project, and our vision as it came together, was a Western that takes place in the middle of this magical adventure," he told Awards Daily.
Release
First-look promotional pictures were released in January 2020 followed by a teaser and trailer in February.

Anglophone reception
Jack Seale of The Guardian awarding the series 3 out of 5 stars and wrote: "But while The Letter for the King doesn’t feel like an adults’ show that kids can get away with watching, it’s also not a kids’ show that’s fun enough for adults to enjoy, with its bowdlerised fights and romance." David Opie of Digital Spy gave it 2 out of 5 stars and wrote: "Unfortunately, The Letter For The King is not the new fantasy smash we were hoping for, so you can toss out any high expectations you might have like a coin to your Witcher. In fact, it's not even that great for fans of the book either.". The Letter for the King was frequently dubbed as a Game of Thrones for children. Patrick Cremona of Radio Times gave it 2 out of 5 stars and wrote: "The show is watchable enough, and might serve as a useful way into medieval fantasy for younger audiences who aren’t yet ready for the more adult-orientated series that have recently dominated the genre, which is by no means a bad thing. It seems unlikely, however, that this is the next big fantasy series that Netflix might have hoped for. The hunt for the next Game of Thrones goes on…".
Dutch reception
Although the series topped the Netflix ratings in the Netherlands, it also received very mixed critical reviews, mostly directed towards the execution of the series based on the book by Dragt. Mark Moorman of De Volkskrant awarded the show 3 out of 5 stars and commented: "With nice young actors, beautiful cinematography and a strong queeste, The Letter for the King is a reasonable success. But it does feel a bit like Netflix has crushed our favourite children's book with a steam driver." Belinda van de Graaf of Trouw also awarded the series 3 out of 5 stars and wrote: "In their dedication to inclusivity, the creators even went further. Tiuri's most important companion is no long a boy but a girl, Lavinia. And somewhere at the end, there is an intimate kiss between two trainees. Sweet, that kiss between two guys, but that scene is a bit unearned. The same counts for all the hocus pocus that the creators added. It is understandable that Tonke Dragt rather wants to talk of series that was inspired by her book than an adaption of her work."
