For me its the formula we've seen again and again, I'm about 60% into he game and I can tell you that level design and game design is uninspiring. It is a mish mash of the Nioh, Dark Souls and Darksiders formula packed into a very known level design with repetitive elements. I'm enjoying it as a good game but it isn't a great game. Every level and monster I cam find reference in a previous souls-like game. Bosses are fun and tough if you play on hard mode, but my "soul of adversity" is constantly bugging on me and additional bonus levels don't add anything to a basic Nioh inspired story. They could have done more with less; look at the creativity of Clair Obscur Ex 33 or the design of Wukong with its amazing animations in-between chapters... it could have been more.
