In Blood and Wine, all is perfect except the final boss fight.
The mechanism of the fight is very disturbing.
It's above all "try and die" mechanism,
as players must try many times for find out the pattern of boss strategy to win.
BUT, each time, we must start over from beginning,
watching the same dialogue, the same plot, and the same animation.
First time, it's so well done and immersive,
Second time, it's interesting to watch again,
Third time and go on, it becomes very disturbing watching the same thing over and over.
At the end, it makes the players ANGRY of this disturbing game experience.
Everything is perfect except the end.

It didn't make me angry, I was happy. This is one of the most attractive bossfights of the whole Witcher-franchise. Wonderful. Congrats, Devs!

All Witcher boss fights are designed this way. I remember pulling hairs in Witcher 2 when I had to fight the kayran or Leto. Unless you do the very specific moves and actions the battle is designed around, you're gonna get your ass handed to you, and you have to watch the whole animation/dialogue/scene again.

I am playing for recreation. Parts I don't like I simply sit out in god mode (for me the mentioned boss fight fits that category).
