They made the amazing story in the books a mediocre show. Nothing makes sense here, starting with the characters, through the story, dialogues, and ending with such a details as lightning. The characters are stiff, there's no chemistry between them. Story changes are dumb, they make no sense. Prostitutes in Kaer Morhen, really...?

It could have been as good and big as Game of Thrones, and it's just your regular, average fantasy show. Just a dissapointment.
