To be honest I was a bit dissapointed with actors. Geralt is good and I think this particualr character does not requier much of effort really. But Yennefer, I'm very sad. I could barely watch episodes where she was depicted and even skipped some of the scenes. I dont blame the actress she is pretty, but in my opition too young and does not have much expirience for this particular role. She sounds like a child and even looks like one a bit. When I was reading books I thought of Yen as a powerful all mighty woman, who can do anything she want's and does not care for anyone's opinion. But in this series I pitied her, in all of the scenes she did not look powerful. I always thought that Yen is a badass but now I have seen her as crazy woman really, that's what I thought I thought that in this series she was depicted as insane and not very logical woman. I have never thought that anyone could pity Yen, but yes, that happened. I'm sorry but I do not like the acting. When I have found out that most of fans wanted to see Eva Green I imidiately thought that it would have been one of the best options! She has that tempter and previously showed it in her works. She could have been way better Yen. I was waiting for these series for so long and I'm afraid the second season will be not worth the wait.
