I loved the game, but, like you, I wasn't massively sold on some of the late swerves.
My problem was that the reveal at the end of act 2 that everything was happening inside a world-within-a-world felt like it cheapened a lot of what had come before that point. I also wasn't a fan of changing the stakes from "save humanity" to "resolve a family drama", which felt very George Lucas.
That was absolutely my problem too! The emotional investment you had from trying to save all of the people you have met is suddenly gone.
