But are people really watching this for the story. I thought they were watching this for the cute girls doing cute things or just girls beating the shit out of each other.
Both things you mentioned can be great qualities of a show, but a good story would just be great for a show's foundation. A cool/interesting story with lackluster action/cute girls can still be fun to follow from start to finish. On the other end of the spectrum, a bad story can dampen any other positive aspects pretty severely.
I personally think a mediocre story would be inoffensive as long it's not distractingly bad, and the characters are great. That's pretty much the blueprint for most slice of life shows.
I really should start watching this series.
