I love DMBJ, so I can't watch this and not be biased. I don't know if it's a decent Drama but it's the worst DMBJ/Lost Tomb adaptation I have ever seen. Including the "inspired" Movie Time Raiders.
Nothing about this feels right, not in the slightest. I don't know if the ML Actor is bad or just not suited for Wu Xie, but it was the worst of all the disappointments in this adaptation. The same goes for the actor of Pokerface.
So maybe it is fun to watch as someone who isn't too much into the Novels or the other Dramas, but for me as a fan of the franchise who has watched literally everything and has read all the novels, this was an absolute failure.
