Like many of these international TV series it is produced at high-budget film quality. I would not have believed that they would find a child actor who could do such a good job of being Anne.
We also watched the first part of American Gods, TV series based on the classic Gaiman novel. Very different, several scenes with a lot of blood, but excellently acted and filmed. And like Anne, it moved at the slow pace of a novel, rather than the frantic pace that often results when someone tries to make a film of a book.
