I'm actually liking the new inspector. I mean, I hate her as a person, but I approve of her as a character. I'd really like her if they didn't feel the need to make her feel like such an rookie. I especially loved Kasei's quote about her after their meeting. Got a good laugh out of that one. I'm also a fan of Kougami's replacement, but I think he needs some more screen time to really sell me.
I like the new villain overall, but the individual things he's doing don't really suite the things I like about him, and tend to be overly dramatic. I'm not expecting too much out of him at this point with 6 episodes left on the clock. Honestly, I feel like the main problem with this season is the damned 11 episodes. I can see a lot of potential, but I think we can all agree that it feels forced/rushed at the moment. The pacing is just not where it should be.
On a side note, for the sake of pure speculation, calling it now, Kamui is dead, and is currently a Robot and/or AI. Or a hollow I guess seeing as the shows obsessed over them so far.
