It's kind of weird. I do agree with many of the actual points people are making. I don't find it quite that "goofy". But it definitely has more of a D:OS feel than a BG feel to it. And this may be the thing I haven't been able to quantify about why it doesn't feel like a BG game—the visual aesthetics of the game.
Ultimately, it is Larian's game to do with as he feels and put his own mark on it. Nothing is a deal breaker (Yet). While I did enjoy the Divinity games I do wish this wasn't so D:OS-ified. PoE felt more BG than this.
