Not very good

In the beginning narration it introduced the all female organisation, why? Why all female?

And they possess power, why? What kind of power they possess?

A bunch of women control and manipulate powerful men, even breeding them and talking about have an emperor they can control. It sounded like they were mentally ill, or they think we are insane.

Without knowing their powers and where those powers came from, it is quite a leap to go along with this.

And they stand next to powerful men, who seemed to be completely unaware of their threats, why? What exactly are their functions, why noble houses use them? How did they get accepted? Simply as lie detectors? Why should they be trusted? Who detect their lies?

They train girls like spies, even a princess train in their school, why would a princess need to be trained like that?

The beginning narrative is like a very lame version of the lord of rings beginning. It is just not very impactful or convincing.

The key to their power is spice, they should have said it in the beginning.

They probably can't afford the same director, but they really should have used the same writers from the Dune movies, this is soap opera stuff.

Then again I am a man, probably not the target audience. I am sure there are a lot of girls into sci-fi, and this show will be a success.
