I've seen 3 episodes of Batwoman. All I can say is that I like it a lot. 
In this Bat-Universe, Bruce Wayne has an uncle (Dougray Scott) and 2 female cousins - Kate/Batwoman (Ruby Rose) and Beth/Alice (Rachel Skarsten). 
The episodes move quickly. Doesn't take much time to set up. 
Definitely far from perfect. 
I can't stand Jessica Jones and Supergirl. But I find "Batwoman" very entertaining,     and it has me hooked.
