These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Big Lipped Alligator Moment: The third Interlude chapter opens with a rather... odd, Dream Sequence Jade was having. It's funny, but kind of comes out of nowhere and throws the reader for a loop. It also features Tarakudo attempting to communicate with Jade in her sleep, only to be ignored and ultimately giving up.
There's also the scene in that chapter where Jade uses her newfound contortionist abilities to win a bet with the Enforcers (see Mundane Utility on the main page). That is never brought up again.
Broken Base: Jade's insanity-induced personality changes in the second half aren't being well received by everyone.
Jade's sudden Straw Feminist personality at the end of the last chapter. Calling Right of all people a "male" as if it was an insult.
Moral Event Horizon: The first thing Lung does after getting more than a single scene per chapter is capture Jade and torture her until she agrees to serve him. And he keeps torturing her when she refuses, even when it becomes apparent that the process is killing her. It's met with a lot of satisfaction from the readers when Right kills him.
Jade arguably crosses it when she forcibly transforms Viper into Hebi, brainwashing her in the process. It's arguable, because she's clearly gone off the deep end by this point, and probably wouldn't have done it otherwise.
Neutral Evil: Blankman doesn't seem to care who's running the Shadow Hand, so long as he's allowed to do his job as foreman. When Ikazuki usurps control, Blankman calmly introduces himself and offers to show him his new assets, and when Jade resumes control, he just as calmly asks if she'd like to get back to some paperwork she'd ditched earlier.
Rooting for the Empire: Most readers support Jade being evil, and wish to see the heroes failing to restore her back to human.
Seinfeld Is Unfunny: Some reviewers said that this story was yet another unoriginal Evil Shadowkhan Jade story. Unbeknownst to them, this fic was one of the very first stories that uses that plot, and due its success it spawned plenty of similar stories.
Selfish Evil: Jade. As Wong explains, she's acting purely on her desires, and anyone who gets in her way is automatically her enemy.
True Neutral: The Brothers of the Three Shades. They'll fight anyone, good or evil, who comes looking for the Teachings of Eternal Shadow. Then, when Jade comes looking for the Teachings, Brother Light initially fights her, but ultimately lets her take them — and when she's gone, he gives Tohru scrolls that will point the way to the other two fragments of the Teachings.
Though it should be noted that the only reason anyone was allowed to walk away with anything was because Brother Light felt they were destined to, and since he has seniority, the other sages went along with it.
