Just finished it. I loved it. Ill give it a solid 8.5/10. The cgi wasnt terrible by any means, i thought most of the monsters looked great and also how they choreographed geralt fighting them it felt real. The only cheesy moment for me was the narrating golden dragon in episode 6 or 7 but that couldve been a story from the books i have to look it up
The timeline jumps did confuse me as well they couldve done a better job explaining that, but once you wrap your head around it , it makes sense. You have to remember before the first novel was written the author was writing a bunch of short stories that involved geralt as a witcher, from my understanding this first season covers those adventures geralt had while also covering the story from the first novel
I also think they shouldve showed us a good look at the map and where exactly all the players in the story are. Game of thrones had that excellent intro that reminded you where everyone was at, you can even tell where characters was at just by the setting of the scene. This show had great visuals of all the different castles and towns, but they never visually title what your looking at you have to catch it in the dialogue
All in all i think it was a great first season, season 2 starts production in January. An 8-10 episode tv show shouldnt take more than 3-5 months of shooting so i think we should expect season 2 this same time next year
