Have to agree with the points in the review, sadly. The game felt like a step either sideways or even backwards in many areas compared to D:OS2, which was at least concise and... genuine? Definite improvements are the level design and, to some extent, companion interactions - but it feels like the latter came at the cost of there being much too little content outside of those. Combat difficulty in D:OS2 was wacky and jumping from really easy to crushingly hard, but it had a lot of fun tactics and interactions you could use with a varying degree of cheesiness - meanwhile BG3's just lacking in difficulty altogether after half-way through, even without the allegedly overpowered things, all you need is a high-level two-handed martial or two and a support caster, plus potions if you feel like humiliating the enemies.
I used to naively assume that the lack of transparency during development was just their approach to, well, development (show when there's stuff to show), but it did get rather suspicious when the first gameplay of Act 2/3 was shown when the game was practically going gold already, and how there were quick cuts of things even then (like, in the Release Showcase PfH you could see how the companions had unique backgrounds, which were replaced with the generic ones on release, not to mention belts, properly implemented crossbows, EA scenes that never returned (fishermen on the nautiloid, Minthara's alternate scene...).
It sure feels like the development was extremely all over the place, possibly the result of Larian growing in scale with so many studios but the management side of things being unable to adapt to being not only so many people in number, but also spread across the whole globe? Plus there's pressure from WotC, and the release date inconsistencies (was it really worth it to give Starfield a cheeky middle finger when the game was clearly undercooked?), and the team seemingly not really knowing what they want the game to end up like (resulting in heavy story rewrites quite late into development so you can see the seams showing, and writing/design decisions fluctuating heavily in quality).
Add outdated visuals on top (some armors (basic chain shirt, Dark Justiciar's...) look downright bad, and it also ties into the whole sex scene/nudity craze - are you really going to use that as a marketing tool when your bodies look worse than ME: Andromeda or even DA: Inquisition, and are devoid of physics to the point of some animations resulting in, for example, females' breasts caving in on themselves?), and the performance issues in Act 3 (didn't get any myself, thankfully, though I was running the game with a 40 frame lock due to having a somewhat older PC), and the final sequence feeling like a poor re-iteration of Fort Drakkon from DA: Origins, and it does not really hold up to being a supposed "standard-setting RPG", unless of course we're implying that the standards got SO low that this is supposed to be a shining beacon of quality.
