As soon as the Ying Ying and Dao stuff came in, everything felt super flat. It was THROWN IN HIS FACE with shit explanation, and they never really went back to fully explain things. They just expect you to respect it as this old prophecy when no one knows shit about it.
They take the Fire Wu out of Uncle Six, he then does nothing, and gets killed. Wtf?
The Earth Wu barely gets to speak before they start fighting. And he never tries to talk to him. For a guy who was all "Let's talk about this" and extremely anti-killing, this makes no sense. And based on what WAS said, the Earth Wu very well could have given up his power willingly, so he could have kept his pacifism going.
The final fight he just tackles Alec and stabs him. Then he goes to slice open his wife? The fuck? This dude was a fucking pacifist a few episodes ago, and his only confirmed kill is the Earth Wu.
They then spend like half the final episode teasing a next season. Which to me makes me think the show runner thought they made some top notch show that was certainly getting a season 2. The show needs a reboot before it needs a second season because so many details were fucking stupid if they made season 2 good, I wouldn't want to ask someone to deal with watching season 1.
