I’m sorry. It honestly ruined the show for me as soon as I noticed. When I first started watching it I was so excited to meet all kinds of varied people, especially from the MCs past, but once I got to Nadeko Snake I was like, “O, it’s waifus all the way down.”
I will never entertain the argument of the person you replied to and your post is exactly why. The originally story being divided into three pieces, is in itself not an actual problem. It could potentially cause other problems, but whether or not it actually does is completely separate.
Remake took me 80 hours to complete (to my non-completionist satisfaction) and had a clear and satisfying beginning middle and end. On this front, I don’t know what you could realistically complain about.
