At least Kirino is great all the time, right?
She absolutely is.
A large portion of the fanbase seems to hate her, but these people are crazy.
I would say the whole second season was pretty crappy. They rushed the material a lot. Two cour series would have been better.
This is true though. I was really disappointed by the second season as a whole. It's still worth watching if you have no other way of experiencing the material, but they left out so much good stuff from the novels and the pacing felt really off a lot of the time as a result. Makes me sad to see a series I love handled so poorly.
Ironically enough, the ending (by far the most controversial part of the series) was probably the part they adapted most successfully.
