The formula still works.
If you enjoyed the previous series, you'll like Worm Valley.
Most of my other review points still apply - the writing is tight, the story has structure and the pacing is mostly very good. The short length really helps.
There's not a whole ton of character development, because the heroic trio are more iconic than dramatic characters. So Old Hu does his feng shui, Shirley kicks and shoots things and Fatty is greedy and annoying. For the most part it works, but sometimes it was a bit frustrating how one note they could be. (Fatty especially could use SOME development)
The production value is great. I'm not sure this even cost that much money, but it looks excellent - everything from sets, CGI to shot composition are well thought out and executed.
This season we even get wonderful rubber monsters (not a spoiler since they're in the trailer) and more!
The treatment of indigenous people was also mostly ok - they are humanized and act both heroic and villainous depending on character. Cool stuff!
It looks like the story is taking us to snowy freezing Kunlun next, and I can't wait!
