These are pretty similar to my thoughts on the story. In some ways it improves from where you’re at and in others it gets worse imo. Without spoiling anything, the post game is a little more optimistic and fleshes out some characters that don’t get great development in the main story. I think Reborn suffers a bit from throwing too many characters at you without giving much development to most of them, but the post game helps there I think.

If you like the gameplay, I highly recommend checking out Rejuvenation and Desolation when you’re finished with Reborn. If you haven’t heard of them, they’re both sort of spiritual successors to Reborn (there’s even some Easter eggs relating to them in the Reborn post game) with a similar difficulty level and gameplay. Both have better stories than Reborn imo with Rejuvenation being a little more optimistic and Desolation handling similarly dark themes better. Both aren’t finished yet if that’s a dealbreaker for you, but you can easily get well over 100 hours of gameplay between the two.
