Strongly agree.
I think the reason for all the positive reception was that the game was decent in Act I and II, though still not in the same class as the old BioWare titles. Act III takes a huge turn for the worst and the endgame is just silly. Everyone unquestionably takes hastily introduced Iovara's word that the gods aren't real based on her eavesdropping through a door, but yet the gods still are real and have power? Your companions all write off the gods but then in the epilogue slides still worship them?
Story dull, vague, humorless and lore-heavy to a fault, writing verbose, NPCs mostly dull, voice acting bad (I winced every time Sagani spoke), few wilderness NPC encounters, weird unfun armor/weapon system, items dull, copper pointless very quickly, Stronghold management pointless, pathfinding broken.
However I did really enjoy the Endless Paths. It felt like I was back in Durlag's Tower. Way more captivating than that yawner of a main quest.
