From the first episode one can feel The Witcher's mood. I'd say Henry Cavill is a pretty good choice for Geralt, and the Witcher's "dance" in battle are well made IMO.

However:

Most characters are not explained, feels like the WoW movie made mainly for hardcore fans.

Plus having this many colorful people in important positions where in The Witcher most kingdomes are highly racists, and in a place based on Medieval Pologna. At least Ciri's Ciri... I'm done trying to justify why this kind of point of view would be racist or not, so just imagine a movie about China medieval era with a black general.
