I watched it last week and loved it! I tried Turning Red, Soul, etc. and never got through those. But this one is my kind of tale! I think it may be because the voice of the narrator is the same as in the cartoon version of The Hobbit, The Lord of the Rings, and The Return of the King animated movies from the late 70s/1980. And pretty sure Gurgi (the furry character) was voiced by whomever voiced Gollum in those features. Watching those movies in my early childhood sparked my interest in Tolkien and his novels. So just hearing the narrator at the beginning was nostalgic for me.
The Black Cauldron story line seems to “borrow“ very similar thematic elements as the Tolkien stories.
