Some people are simply better at writing stories than other people. Some people are more tolerant of bad writing than others. You really, REALLY hate this game past the point of no return, so just drop it. This game is not going to change dramatically this late in the development. You need to forget about this game and move on.
This is no longer a debate about the game; this is life advice.
I had a seething hatred for this one manga I was reading, and I kept reading it due to sunken cost fallacy. I spent a lot of time criticizing it, but then I realized that I didn't have to ruin my own day by spending time hating something I disliked. I just dropped the manga, forgot about it and my day was better.
