not because of a size of the intended audience.
That's...depend.
For the same reason because people like Fast & furious but don't like Birdman.
But yes, the problem is for sure internal. About the Wild Hunt expecially. But even Menge or Whoreson Junior could have been handled better. Or the Sabbath.
But expecially some choices and consequences. I mean...Brothers in Arms...it's useless. There is no consequences, is just useless. Nothing change if you gather allies or not.
But it's even external. Because you just cannot make retcons and mix of different choices.
You have quotes about Vergen even if you choose Roche path, and quotes of the assassin of Henselt even if you choose Iorveth path. A no matter what you choose, Geralt still ask about Saskia to Philippa, even if you released her from the sorceress's control. No, it's simply a mess, and the import save is a joke.
There is only one way to handle a choice from the previous game.
The fall of House of Reardon.
