I put 50 hours into it then put it down because I hated how tedious it became, and didn't particularly like the writing either. Divinity Original Sin II is MILES better than this game.
Other way around for me... Sure the second game is arguably better, but I completely lost interest at one point. LOVED this one. The mockery throughout it all is great to me here, it is completely embraced in the whole game and it's lovely. Best characters too, where in the sequel the characters felt so generic. Perhaps the second game is a bit more serious, but it just didn't really worked.
Also, I think a lot of the old school tracks from Divine Divinity and Divinity II (not to be confused with Divinity: Original Sin II) were replaced.
That excuse has more holes than this fine slice of Gorgombert.
