Since no reviewer here seems to have read the original novels, I will try to my best: The Idhun Chronicles (or Memories from Idhun) is a fantasy trilogy, written by Laura Gallego (Spain). The original books are good, not perfect, but pretty good. But this adaptation is not worthy. It´s very difficult to explain, but I would say this is similar to the Avatar: the Last Airbender live action movie (the story is similar, but not quite. The characters are more or less the same, but at the same time they aren´t. It´s like all of the heart was taken away from this project). One of the worst parts is the voice acting: the author of the novels was originally involved with this series, she even casted a bunch of legendary voice actors for the show (the voice of Saitama in One Punch Man as the main character, professional voice actor Michelle Jenner (Hannah Philips in Toy Story) as the main female character... But the production company decided to fire all of them last minute, against the wishes of the author. And they casted a group of models, rookie actors and social media influencers instead (who never did any previous voice work), and it shows. Not only that, but this is the first animated product ever created by this production company. This not only lead to a lot of online controversy (since Laura Gallego was very open about her disappointment), but it also lowered the general quality of this show. My conclusion: You will only enjoy this show if you completely ignore the books, and you´re a BIG fantasy fan, but don´t think this represents the original story. There are a bunch of unique moments in the books that were slightly changed in this series, turning them into grey and generic (like the opening scene: I always thought the start of the first novel was pretty original, but in this series it was changed to the most generic main-character introduction ever). But to each his/her own.
