You know who I like?
Chihaya Kisaragi.

While it's hard to pick a favorite iM@S girl I'd say she'd be probably be the closest.
Her arc was extremely well done. As it had proper build up, was written well, and the characters acted pretty reasonably given the situation.
This...is basically a poorly done version without anything that made Chihayas arc any good...But it does give more backstory to the Producer.
We continue with Mio's disappointment with the audience number of her mini concert. So she pledges to give up.
Which leads to Rin giving up.
So the Producer has to fix it.
Which he does. But really this whole scenario seems completely contrived. Nothing before implies Mio would have the problems she does. So it just comes out of left field.
I'm going to stop here for tonight.
But if it's not obvious, Cinderella Girls hasn't exactly surpassed iDOLM@STER Classic in any way so far.
It feels very paint by numbers. Which is why I have so little to say about it.
