Honestly I feel like I still liked the manga all the way through.
However I give a ton of credit to Gotouge for knowing she needed to end it when she did. I think any attempt to keep it going would have been disastrous, and it must have taken a lot of will to stick to her guns when at that time people were talking about Demon Slayer like it was the next One Piece. I'm sure Shueisha wasn't happy!
