I don't mind the pajeeta as Yennefer. Except she should be pale. But the big problem is that she looks like a frightened lamb most of the time. I don't think she grabs Yennefer's essence.
As for Ciri I can say the same. As for looks fine, but looks out of place in that role. They should have picked someone with background in martial arts. She looks ridiculous with swords and shit.
As for Triss. She is so awful I won't even search for a photo.
And Dandelion, whom they never call Dandelion, he is just gay. Flamboyant gay. Sure he shouldn't be witcher type of manly, but he still is someone who can seduce any woman.
Somehow they took all the characters and they made lame imitations out of them.
Not to mention that Geralt should be the main hero, but everyone else is in the forefront. This should be an action fantasy with dramatic elements, instead they give us melodrama with couple of Geralt fighting scenes (the rest of the violence done doesn't worth a mention).
