I worked that out when I stopped watching.
The production really quickly changed from 'lets do awesome stuff' to 'standardized. Conform. Money. Money. Conform.' bullshit when RT sold out to that other company.
E: just marathoned episodes 5-12
Well, that was nice. Episode 7 was awesome, nice fight scene.
I liked the new Grimm too.
I dunno, overall I was satisfied with this season. I liked it more than I liked S3 anyway. Much better pacing, voice acting has improved immensely. About time tbh.
