I know what you mean, it's a bit sort of generic Anime.
There's such a wealth of incredible artwork related to LOTR, both illustrations from the various publications and all the stuff from the films, that this just looks a bit amateur in comparison.
According to IMDB, the animation studio is Sola Entertainment, which really doesn't have much under their belt. They are listed on "Ninja Kamui" and "Ultraman" and thats about it. I cant say much where the staff came from or if there is any famous directors behind this but they seem good enough. The bar for new LotR content isnt that high right now so ill be happy if its the quality of Netflix's+Anime colabs.
Edit: also post-production notes say late-december 2024, and its expecting a theatrical release (good luck with that...)
