Can't say I was a big fan of the show to be honest.
Very clearly trying to piggyback on the success of Game of Thrones, not that there's anything wrong with that per se, but it was too grey and brown, lacking the colour and charisma of the games. (Yes, I know it's based on the books, but still, the grim desaturated thing is overdone and boring and a livelier look and feel would've been a lot more compelling)
Henry Cavill was actually surprisingly good in the lead role, but Yennefer was an unlikeable bitch, which is a problem as a lot of the show rests on her. Renfry was way more sympathetic, interesting, and attractive,
which is again is a problem when your most appealing character lasts all of one episode.
