Can someone explain the appeal of the Witcher as a series? I'm thinking about finally taking the leap.

The writing.

It's perhaps one of the most well written series in my opinion. From Geralt's dry dead-pan sarcasm to the complex interwoven world in which he inhabits. Stood up against mainstream contemporaries like the Elder Scrolls, it's an unrealized standard I feel.
