Big disappointment for me, especially since the wait for this was so long.
I really liked the original source material, their was absolutely no need to change it. BUT I would have accepted a new take if it had been good. This however was not good, not even close. It seemed to be an attempt to fill holes/mistakes that were made in the Witcher episodes. Or an attempt by writers with no understanding of what the audience wants or an appreciation for what made this story so loved and successul prior. The rest of my feelings mirror what many have already said. This was very rushed, and none of the characters were allowed to develope. You feel no emotion or connection for them at all. The pacing felt so chaotic that characters changed in an instant without reason. The dialog was not well written, which created some cringe worthy scenes.
All and all poorly done...Skim it so you know the origin for The Witcher Series (not the real origin). No other reason to care.
