Halfway through the first episode of The Witcher (had to pause to watch the Wanderers)
So far it's pretty good. Henry Cavill isn't perfect for Geralt but he's still really good at the role. I don't think you could find a perfect Geralt. May have been better to have him play another new Witcher especially considering they changed so much of the story.
The show is flooded with law though. 20 minutes in they've covered mages and sorcerers, Nilfgard, many different monsters, the Wild Hunt, and a crap load of other things. But they aren't treating it like a tutorial. If you have played the games you'd be confused as hell over what they're talking about.
Main downside, Geralt has only one sword. That's pretty much sacrilege. The sword also randomly vanishes if it looks too weird in the scene.
I do like Ciri, even though she's a younger version, the actress plays her really well.
I think the show has much promise.
