I couldn't tell you specifically about it feeling like a BG title, but I can say, as the flip side of your experience - I'd complain that it struggles to really feel like a D&D game, speaking as someone whose majority experience is 5e itself; it really has only a ships-in-the-night passing acquaintance with the 5e rule set, and it's still very visible that this game was built on the D:OS2 engine, and has had elements of D&d shoe-horned into that, rather than having an engine made for the game.
