Finally some "mainstream" press acknowledgement of act 3 issues from (ahem) Forbes:

"2. Act III Is A Total Mess
Crashes, screwed up quests, pacing issues and more make Act 3 a real slog to get through, and I’m a little surprised that so many reviewers have given this game a 10/10 with Act 3 in such rough shape. Frankly, it doesn’t seem that Baldur’s Gate 3 was actually ready for release (despite years spent in Early Access) and this was rushed out the door prior to getting the necessary polish."
