I havent read any of the books --Yet . Have played 'the witcher 3 - the wildhunt' so its sorta like having a series based on a video game but its obviously not. If i based the story in the game , the characters etc then by this alone they have blown my expectations out of the water. Henry Cavill - i was majorly sceptical in the screen test he looked like legolas's older jacked brother and not the grizzled monster hunter/ warrior/ misanthrope. But i was pleantly surprised , yes he has a tom hardy - bane kinda change of voice but he aces this role - Hes geralt - period, hes ace in this role. The supporting cast are brilliant they all really work to make sure none of them come across as 2D or flat. This is a solid sound series, if you like monsters swords and fantasy with a good deal of sarcasm and side eye at the right moments. Definietly watch this show.
