I don't understand the GoT comparisons. GoT is a show about politics where the main "character" is the Iron Throne, the Witcher is a show about the adventures of Geralt of Rivia.

I found the show addictive, watched all 8 episodes in just two days. My only two complaints are how the show sometimes feels rushed and the cast diversity. The Witcher is based on Slavic mythology and is set in a fantasy version of medieval eastern Europe, not exactly a diverse society so diversity in the show just feels forced.

The show in my opinion has great potential and season 1 was a good base to build future seasons on.

EDIT: After season 2 I'm increasing the score to 9/10. Loved season 2.
