Yes, I do find the doomsday prophecies very tiresome. Most people can already tell that this game will be a success. The question is how big is gonna be. And it deserves criticism of course, why it needs it, that's the point of the EA. But still, acting like BG3 won't be a successful entry for both Larian and DnD games, is just not realistic.
Don't know what "most people" mean, but the state of the game for 4 years of development definitely isn't good. It still only has 1 act, lacks half the classes, a proper reaction system, day/night cycles and still doesn't play like 5e D&D. On GoG it has a score of 3.8/5, or 7.6 which in my view is a disaster for a game with this legacy. And most of the criticism in the reviews is the gameplay and comparisons do DOS, which the developers still insist in not addressing.
