The character building was done pretty well through the beginning parts IMO, which were episodic in nature.
I'd rate the show a 7.5/10, or maybe an 8 on the days when I'm feeling generous. Either or, not much of a big difference anyways.
Also, from what I can tell, you will get a lot more out of this series if you're either a) A fan of Spaghetti Westerns, or b) A yuri-tard
Show must have been bliss for the fans of both... if such fans exist?!
