Not finished yet but I do think overall the quality and acting has been a bit better than season one.
The problem I have is I think things start to fall apart a little when they veer off from what has been written. Shockingly (not), this is where GoT was weakest as well.
The material with Geralt and Ciri is *chef's kiss*
When it starts getting into the mages and Yennefer, etc. I personally begin to get bored and I can see how the writers were just filling stuff in. And then I think "this is why you should have just stuck with the material provided."
I think Lauren and co. are having to unpack too much on their own by trying to make the show about Geralt, Ciri, and Yennefer equal across the board. It's almost too much screen time for all three and just dilutes things, in my own opinion.
