I read some of the user reviews and i think significant amount of people who played the video game are not so pleasant with the show, i get that. I understand what makes them upset. They have an image of the characters, their aspects so on and on. The characters on the show might not live up to the espectation for the people that played the game.
I on the other hand i didn't play the game (i guess i should thank to my father for not buying me a playstation 3). Later i become a huge pc gamer and console gaming ended for me before it even started. My point is i am thankful that i didn't play the game because i am loving the show and i believe everyone who didn't play the game are enjoying themselves as well. I think it's because we don't have any reference point to compare things. From a neutral point of view i think they did a very wonderful job on this series. I am sure it will hold the standards throughout the season finale or finale.
Just wanted to point out i once was in your shoes with the witcher series. In every aspect you can't compare the quality of this adaptation no matter you played the game or not. I believe if you watch the show, then play the video game it will be more optimal experience.
P. S: It is coming to pc in a month so be ready guys. Much love.
