AC VALHALLA is Amazing. Why so much hate!?

I held back from playing this game due to everyone talking smack out it. I recently began playing it and it is simply AMAZING imo. I just finished the part where Oswald and Rued fought to the death and simply WOW. I know Ubisoft are bad with their practices so Im not praising the company. But so far, this game is really a masterpiece.

I don't understand why so much hate. The story is honestly very good in my opinion.
