Even if you ignore the outright ridiculous twists, the main story is just another generic tale of EVIL monsters doing EVIL things for the sake of EVIL, because they are EVIL. People were (rightly) criticizing the endings of Mass Effect 3, but those at least raised some interesting questions. Here you get nothing thought provoking. The story of BG3 is so shallow, that I have trouble believing that there wasn't a game this year that told a better story.
