I am not into anime and do not know much about it, but I like the Witcher universe and it didn't take long before I was fully submerged despite this not being live action.
The story is very short and predictable, but not entirely bad. As I said, I like the Witcher universe and the story takes you through some of the background of the Witcher guild.
It ends with a nice tie-in for the start of the relationship between Vasemir and Gerald, whom we know from the Netflix live action production.
