I'm not sure if there's ever been a game with a larger disconnect between the time that could and should pass on your adventures and the time that actually does, because time is basically "frozen" on the same day until you go and rest. If you hike from the Nautiloid to the old temple where you meet Withers, then move on to the Grove, explore that, talk to the people, maybe even clear out parts of the Blighted Village - well, that's like a couple of hours of real life cRPG time, but in terms of any regular PnP campaign that would be several sessions, easily, and quite a lot of time for the characters.
That's just all not very well designed, at least not for me and my preferences. Act 1 is basically the sum total of all Baldur's Gate wilderness areas stitched together, forming one giant map, with the really big holes of nothing removed. It is a super dense blob of things to do you're thrown in with no sense of time progression at all (mostly because there really is none, aside from the game's internal round counter and a pseudo-advancement of time when you go to camp and come back without resting) and arguably worse, no clear sense of direction.
Baldur's Gate at least was nice enough to provide you with a destination and a trail to pick up that would not prove to be overly problematic to your party. You could vector away from that, of course, and run into your fair share of maps you should not be in and find yourself fighting Ankhegs or getting wiped out by Basilisks with your trusty level one group (although those Basilisks make for really good experience even with very low level characters once you know what you're doing) but if you follow Baldur's Gate 3's meager pointers the game - quite literally and in a break of immersion - tells you that your party is in for a really bad time if you move on or you end up potentially facing a hike in encounter difficulty that puts the Owlfinder games to shame while trying to solve the Druid Grove's problems.
All things you should logically prioritize because the game drives home how much of a priority they are. Instead you have to go on side adventures to reach a good enough level. Well, have to, there are ways around everything, as always, but as far as the "intended" way to play the game goes, I have no idea how it got all those glowing reviews. Yes, going to the Friendly Arm Inn and then to Nashkell without spending some time poking around in Beregost would net you two pretty annoying battles with assassins in Baldur's Gate that could potentially be devastating, but they're nothing compared to the killer sheep in Larian's game.
Then again, I don't know how glowing reviews come to be for a lot of games, TV shows and movies, so clearly it is not just the Baldur's Gate 3's problem.
