I totally understand your point of view because I have nearly the same experience than you about BG1/2.
But I have to agree with others (and I don't often agree with some of them^^), the rules had changed, and that's good.
This is a little bit disturbing but the more I try to understand those rules, the more I think they're great for a video game.
That said, it's only about the rules and that's not your entire message...
About exploration, I totally agree with you. The feelings in BG1/2 were way different than here. Again, the worldmap is USELESS, as in DoS and I'm very dissapointed about that.
BG3 deserve something better than a cosmetic worldmap... even if the structure of the maps/act/region won't change.
At least I really hope they'll change their awfull MMORPG fast travel system for it to hbecome a part of the worldmap. Better than nothing I guess.
I also agree with dialogs... and even more because I read them in french... And I read way faster than they talk... and I don't always understand what they say

Even for a totally useless dialogs, you have those cinematics (hello the 2 characters dying on the nautiloid), fully voiced to say... nothing interresting...
This is a waste of time and a waste of ressources... Those cinematics are great but should stick to interresting, related to quests, lore and that kind of things...
Someone that say "I have nothing to say, you just loose 15 seconds" should say it in a popup, not in a cinematic. Gonna be fun when we'll reach Baldur's Gate....
I also agree woth the HP things but I think things has to be balanced.
There are too many things to keep your HP high during battles ("oh wait, I'm going to eat an apple before I try to hit you"), and even with that you have to rest everytime because of your spells...
That said, please try to reconsider things and think about the game in a few days/weeks.
Maybe I'm too optimistic but I really think it's still time for it to become a legendary BG new gen.
Of course many things have to change according to me and Larian has to hear/understand why BG1/2 are still in the head of so many people... and why it became legendary games.
