I watched this drama a pretty long time ago, but regardless, it is still holding the top spot for me. Being completely honest: the visual effects may be lackluster to some in comparison to more highly funded shows, but it definitely does not reflect negatively on the story. This story has taken quite a few forms - from a novel, to an audio drama, to a show (holding the same voice actors), to a donghua (Chinese animation) and not once have I grown tired of the main leads, the story telling or world building. This is why I gave it a good RWV rating. BUT that is partially because, although I've watched it alone at least 2 times fully, I MAINLY watch reactors. In that way - I feel that the re-watch value is up there.
For anyone doubting whether to embark on this journey or not - I think that if the idea of satisfying visuals set in old China, fantasy, censored (but still sweetly portrayed) queer relationships, amazing world-building, HIGHLY lovable leads, in depth character growth, good acting and some spectacular villain stories intrigues you, you should give it a go.
On the off-chance you've watched Word of Honor or Guardian, which I highly recommend btw, I would put it like this: Guardian walked so that The Untamed could run, and The Untamed ran so that Word of Honor could become a track-star.

(and no, I hadn't watched anything and did not have any other context of the story prior to watching the series. I actually found out about it through youtube and fan-made MVs.)

This review might've made no sense, but seriously, if you are a BL fan or simply a fan of fantasy dramas, please give this one a go <3
