If it weren't for the obviously substitution of original characters for diversity sake this show would be a ten out of ten. The author of the books is Polish and based his fantasy novels on Polish medieval mythology. Therefore, the books, and the video games based upon them, featured the humans as white Northern Europeans. Hollywood's edict of adhering to affirmative action--once reserved for only government institutions--to be eligible to win awards forces producers to hire people of color for roles not originally meant for them. If you are familiar with the source material then every time you see characters like Frangilla or Triss (to name a few...trust me) the immersion is immediately broken. You can't help but say "Yea the actress is acting the part well but LOOKS absolutely nothing like how the author described her in the books or how she appeared in the video games." I am sorry there are no popular African medieval fantasy movies based on novels for people of African descent to act in. However, that doesn't mean they deserve to be shoehorned into existing stories where they never existed and don't belong.
