The story of this movie was great, but that's not to say it fits with the main story of the Witcher, which symbolizes hate for one who is different. It is hard to describe what I mean without spoilers, but yes this is a good movie with a great plot.
(you still not might understand what I mean after watching the movie)
I personally do not like anime for it takes away from the emotion and also subtracts uniqueness to characters. overall the anime in this movie ruined much of it for me cause like I said earlier, it affected the characters in a negative way. I wish this movie was simply just stylized animation.
If you like anime or just don't care about it, you will enjoy this movie.
The movie has unnecessary violence and sexual graphics, I see why they added it though; the Witcher is not a family friendly franchise.
