Review Detail of Rudem in Thriller Paradise

It started very well, I thought I had found a masterpiece like LoTM, but the development of the MC made me want to abandon it, in the start he just had some mental problems that didn't interfere much with the plot, but then he goes literally crazy and starts imitating the joker, the story was well written and promised to be a masterpiece, and I believe it is, but unfortunately it's a masterpiece that I couldn't finish. Lots of useless information, lots of irrelevant characters, and lots of filler, we are presented with so many characters that it's difficult to know who is who. I have a strange feeling about this novel, usually the novels I abandon have a good premise and the author simply ruins the story. But this one is different, the author is very good, the story is very good and everything is cool, I just wasn't at all interested in knowing what was going to happen in the story. I feel strange.
