Does it have the same feel as BG 1 and 2?
Not even slightly.
It's a completely different tone, because Larian have very different writers to Black Isle 20+ years ago.
Initially the writing had a downright nasty tone, nigh-identical to Divinity: Original Sin 2 (DOS2) (where every option tended to be a bad option, just bad in a different way), but the Early Access gave a massive pushback against this and steadily over the course of EA the writing and events got tweaked and changed and modified and you gained a ton of options to be nice, or pleasant, or reach a purely-good outcome (rather than having constant morally-grey compromises forced on you). NPCs became less needlessly antagonistic - a prime example being Shadowheart, who changed so much people were saying they kind of missed her unnecessary jerk-ish-ness (you can still get it if you treat her poorly - but before she acted like that no matter how kind you were).
Also in Act 1 it's considerably less "Forgotten Realms-y" than BG1/2. However, again I have to note that as the Early Access went on, this situation did improve somewhat, and it's even possible that Baldur's Gate itself will be more accurate.
The most bizarre decision remains that they've basically made the terrain look like one of the rockier quasi-arid parts of Spain. Literally everything we know about the Baldur's Gate area in the various RPG supplements which discuss it indicates it's extremely wet (like, constant rain) and very green, which the game absolutely is not. Nor has there previously been any suggestion that the area is rocky. In fact the direct contrary - it's supposed to be rolling hills and flatlands.
There are other major differences, which I would say were largely for the better. The primary one is that BG3 is more like Ultima 6/7 or an immersive sim* in that you can actually use the world and things in it do achieve stuff, and you can often come up with some pretty tricky shenanigans - though more working out ways to do things or approach places than the mindless and repetitive "LOL I SURROUNDED THE NPCS WITH EXPLOSIVE BARRELS BEFORE TRIGGERING THE FIGHT I AM THE SMARTEST AND MOST ORIGINAL MAN ON THE PLANET" which characterised virtually all of D:OS1 and some of D:OS2. There are also far more solutions to most situations just written in and coded for than in BG1/2.
So if you're looking for another BG game like the old ones, BG3 ain't it.
If you're looking for what is, so far, an extremely good CRPG, albeit one that started off not very BG/FR/D&D-ish (before improving), though, BG3 is it.
* = The one major thing missing compared to them is there is no day/night-cycle - it is perpetually about noon outside of rare scripted scenes - and there is, at least in Early Access, no dynamic weather, just a tiny bit of scripted weather.
