This could either be really good or horrifically awful. However unlike The Witcher show, I feel like it has better chances. Source material doesn't matter too much in that V's story can be pretty dynamic with how its told and The Witcher has a very linear story line and strongly solidified characters.
Adapting existing stories and changing them has to be done really well for people to appreciate it and The Witcher just didn't have this going for it. 2077 on the other hand has so many places it could go, characters that we've yet to meet. I mean really they have all the options as long as the dialogue and delivery is done well.
