I love how cinematic BG3 is, and for me it definitely enhances immersion and brings the characters and story to life. Which isn't to say that I need fancy graphics to appreciate a cRPG - I've been a fan of the BG games since they came out and enjoyed more recent games like WotR - but I do think they take a game to another level. And I am very glad that Larian put the effort they did into creating such a cinematic experience. Maybe I wouldn't be if I didn't like so much else about the game, too, but unlike some I definitely don't feel that BG3 is style over substance but enjoy the story, the characters and the gameplay too. And the cinematics for me enhance the first two, at least, considerably.
