Finished it up - overall I thought it was good, but not great. Maybe 7/10 overall.
Cavill was awesome, the scenery was great ( particularly the castle they were defending, although they obviously didn't have permission to film inside it ;p ), fights were great, overall effects were good, nice tits were a pleasant surprise.
On the downside the storyline felt really disconnected - not quite standalone episodes, but not quite an overarching story either. There seemed to be some weird contradiction in there too - like Yennefer whining about how she didn't get a choice about babies, when like two episodes ago she forces the guy to do it, the guy clearly and straightforwardly explained it to her, and she said fuck it, I'm in.
Game of Thrones production quality really hurt future fantasy shows though, this didn't have the budget to compete, and while it would have been great if GoT didn't exist, now the costumes and set pieces just seem a bit cheap.
Acting wise was a pretty mixed bag, Cavill obviously great, Renfry was good, Yennefer was fine, Ciri was fine, Fringilla was bad, Elf boy was godawful and made no sense ( Hi, I rescued you just so I could tell you to go fuck yourself to your face - see ya ).
