Personally, the series stagnated after episode three.
I'm not denying the fact that there has been overall development in the past episodes, but it doesn't really feel like it's going anywhere, at least when it concerns Kirino/anything directly connected to Kirino outside of Kuroneko and Saori (the latter appears to have a dedicated episode coming up so that will be interesting).
Also, the news concerning the attempts at two different endings when the actual serialization isn't over to begin with is...
