It's mostly based on the Kids games.

I haven't read the books, mostly because they are Polish, so for most people they know The Witcher through the games by CD Projekt RED a Polish developer.

The First game was a Buggy mess that had something.

The Second game was very polished ( CD Projekt RED had learnt how to code now😊 it had a good story and great game play, but somewhat linear ( I prefered the second game )

Witcher 3, still stands out as one of the best games ever made, the character models are starting to date but it looks amazing, it went completely free roam and open world, but I found the story a tad long winded and combat shallow and overly a little taxing and boring at times. I completed most of it maybe 80% and gave up, I still sometime think about reinstalling, but just cant be bothered

So that's IMO on the games.

The TV show is shallow with the wrong cast, it sits between Hercules: The Legendary Journeys, and the BBC production Merlin, it felt kinda cheap, and had the Netflix stink to it, where they can take a 2 hour idea and stretch it out over 3 seasons.

If they tones it down just a tad they could show this on CBBC or Disney Channel, it's a kids show, and not the graphic, crude, rude and violence that the games and books are based on..

But hey its on the same level as Doctor Who, so now 12 year old girls have more shows to watch which is nice.

3/10 for effort.
