## Premise

Over the course of the series, she and her deerfox Twig, later accompanied by an elf named Alfur, and best friends Frida and David, go on a number of adventures interacting with and befriending the mysterious animals, people, and spirits that live in and around the city of Trolberg.

## Production
### Conception

Luke Pearson had previously worked in the animation industry beforehand, serving as a storyboard artist on several Adventure Time episodes. Early on in the Hilda series, he never seriously considered an animated adaptation of the books, though he did have a few thoughts about how the character could work in animation even before he worked on the first comic.
Before being approached by Silvergate, there had been some interest from a few production companies about making a Hilda adaptation, though nothing had ever been agreed to. Pearson felt as if those other proposals skewed the idea of what the Hilda series is supposed to be, and that they felt off, only leaving the outer shell of the idea and changing other fundamental things.
In 2014, Silvergate producer Kurt Mueller found Hildafolk, the first book in the Hilda series, at a US indie bookstore in Brooklyn, NY. Producers at Silvergate loved the book, and were interested in bringing it to television.
Later that year, Luke Pearson received a proposal for a Hilda animated series from Silvergate through his mail. The proposal pitch was styled as a book from Hilda's satchel in Hilda and the Bird Parade, even coming with a Trollberg library card and a small elf letter inside, as well as a wooden USB stick that contained the actual pitch. At that point, three books in the Hilda series had been published, with the 4th one, Hilda and the Black Hound, being worked on at the time. Pearson enjoyed the proposal, and soon discussions began with Silvergate.
When Pearson and Silvergate started working together on a pitch, they wanted to build upon the original books while simultaneously keeping the general feel that the series had. Luke was specifically concerned in making sure the show didn't feel "too TV and formulaic."

### Pitch

With help from head writer Stephanie Simpson, Luke and Silvergate created a pitch bible that would be used to pitch the show to various broadcasters. Some elements from the books were expanded upon to help fill out the show. For example, the characters of David and Frida were originally minor characters that appeared in The Black Hound. Simpson specifically picked those characters out and expanded on them so they could fill out roles as Hilda's friends. Netflix eventually picked up and greenlit the series in 2016.

### Announcement

Development of the series was first briefly mentioned on June 15, 2016, in The New Yorker, stating that Netflix was planning a "twelve-episode animated series, based on the first four books, for early 2018." On June 21, 2016, Luke Pearson and Sam Arthur (co-founder of Nobrow Press) announced on Nobrow Press' official blog that Silvergate Media would also partake in the series' production, with Pearson saying:
   I'm obviously very excited to be able to finally say this is happening. Alongside drawing a new book I've been working with Silvergate on this for a while now and can confirm that it's in unbelievably good hands. An inordinate amount of love and attention to detail is going into this thing and I'm looking forward to sharing the result in a couple of years' time.

### Animation

Mercury Filmworks, a Canadian animation studio known for working on various animated Disney television shows, came on board early in development. A minute-and a half animation test was created to figure out how the show would move and look. There were various experiments with the show's design and art style to see what would work best for the adaptation. Additional animation was provided by Atomic Cartoons, who helped animate 8 episodes from the first season.

### Design

When it came to designing background characters for the show, Luke would usually create preliminary sketches for a character, and it would then be translated into a finished design by Mercury. Some characters were given dot eyes as to help make characters like David better blend in to the style of the show.
The creatures in the show, as well as the book series, are heavily based on Scandinavian folklore. One of the biggest inspirations used for the show was Scandinavian Folk-Lore: Illustrations of the Traditional Beliefs of the Northern Peoples, written by William Alexander Craigie. Many creatures in the show were taken directly from these tales.

## Release

The first two episodes of season one premiered at the New York International Children's Film Festival on February 25, 2018. The first and third episode of season two premiered at the NYICFF on February 22, 2020. The first two episodes of the third and final season premiered at the Ottawa International Animation Festival on September 21, 2023, the series' fifth anniversary.
The first season was released on Netflix on September 21, 2018. The second season was released on December 14, 2020. The third and final season premiered on December 7, 2023.

## Reception
### Critical response

Hilda has received critical acclaim from critics and fans of the Hilda books, praising its writing, characters, animation, and vocal performances. On review aggregator Rotten Tomatoes, season 1 has received a 100% fresh rating based on 10 reviews with an average rating of 9.00/10. The website's critic consensus reads, "Animated magic of the highest order, Hilda successfully captures complex feelings and charming characters into an enchanting adventure that is suited for children and adults alike". Emily Ashby of Common Sense Media gave the series four out of five stars, stating that Hilda, herself, "is the show's best quality, but it also benefits from curious characters, exceptionally matched storytelling and Toonboom animation, and an endearing world of fantasy".
Allison Keene of Collider gave the series a four out of five stars, saying: "Regardless of age, Hilda invites viewers to join in the mystery and thrill of adventure and to find the magic in the introduction of these many creatures, and some of their curious habits, in an upbeat and wonderful world. Though Hilda must grow up and accept city life, she need not put aside her childlike wonder. Neither should we." Others focused on the character known as "The Librarian," (later named Kaisa) arguing that her character is "among the most positive pop culture depictions of librarians, along with fellow animated shows Cleopatra in Space and She-Ra and the Princesses of Power." The same reviewer states that the nine minutes in the first season within a library setting makes a "strong impression," including an episode featuring a special collections room, and arguing that the series makes clear the "importance of librarians and libraries for years to come."
