It was good, but S1 was very confusing if you didn't read the books.
The first 2 books, on what S1 is based, is a bunch of short stories with the witcher. So it jumps around in time and you get it because every chapter is its own, separated story.
They should have framed it as Jaskier telling stories of the witcher and Yennefer and it would have removed so much confusion
