BG3 is a story about Redemption or Damnation. This is spelled out early on in dialogue. If you don't like stories about these themes, then its like reading an Agatha Christie when you don't like murders.
The problem here is the writing isn't of sufficient quality to make redemption a proper theme. Planescape Torment was able to tell a story like that, but what we have in BG3 is a bunch of disparate stories of people who have no reason to attempt redemption attempting redemption. The story just doesn't hold together like that. It's a story that only works when its about damnation. You can argue that it should only be played by people who are interested in stories about damnation but we get rpgs of this scope once every decade or so, just not playing it is an unsatisfying answer.
