People who don't like this game are disliking it without actually having finished the game. It was massively review bombed within hours of release when the game takes 30 hours to complete.
The story shows the perspective of both sides of the conflict, rather than simple black and white one dimensional characters. The subtlety of facial animation allows higher emotional expression and portrayal of internal conflicts of all characters.
Gameplay is great and allows for wide variety of approaches to pretty much every single combat encounter.
Graphics are gorgeous, with highly detailed, lush nature environments contrasting with gloomy decay of human settlements.
Minimalistic guitar score makes every note that much more impactful.
I would definitely recommend everyone to experience this game first-hand to fully appreciate the effort and quality of it.
