Having not played it, I'll stick to using a review I read in the past few days.
To sum it up, the game felt too positive to the reviewer. To them it felt more like a Disney adventure than a grim fantasy world that's invaded by malevolent, torture-happy evil gods. They felt no bite from their choices, from the story or from their companions. Everything felt like it needed to be happy in some way, like the idea of conflict was a far more terrible outcome than being skullfucked by an angry tentacle god lady.
To sum it up even further, the game felt too safe. And so became a bland meal that's easily forgettable.
