As a huge fan of the Witcher universe I can say it's rather frustrating to watch.

Some of the cast is well suited to their roles (Geralt, Ciri, 'Jaskier' ), while others don't look even close to what they're supposed to (Triss, Fringila, Foltest, Filavandrel, Phillipa Eilhart, the list really goes on).

The writing and the dialogue is also pretty underwhelming. The story is all over the place and it deviated really far from canon material. It feels written by people who don't like or care much for the original world.

The acting though was great from most of the cast, so my respect goes out to them, but sadly it wasn't enough to provide an immersive experience given all the other faults to the show.
