For the first season it was more than enough to keep you interested and wanting more. People who are new to the witcher universe specially will probably enjoy it the most.

However if you are familiar with source material there will be things that annoy you.

Geralt , yaskier and yen characters are done perfectly and other characters are rather good for the most part.

As a long time fan I had 3 major problems with the first season : 1- Ciri's story in first season was bland. They should have kept it for second season. 2-Time jumps were confusing 3- Triss merigold character was the most disappointing character in the series for me. From her looks to personality it didn't match the character we know for long.

I hope they improve in the second season.
