I finished my first playthrough, I will write a proper review once I finish one or two more playthroughs because there are a few things I want to test out first but here's a quick summary of my thoughts on the game.
The game is overall fine, nothing groundbreaking but reasonable solid for the most part. The weak point is the combat as 5e combat is incredibly shit and despite Larian's best efforts they could only barely improve it.
The final boss is one of the worst experiences I've ever had playing a videogame.
