YMMV / Cheat Slayer

• Audience-Alienating Premise: Fans of isekai works were turned off by the inaccurate and mean-spirited parodies that painted the characters they were familiar with as a group of utterly horrific monsters, whereas general audiences were turned off by the excessively grim tone and graphic content (for example, the plot begins with the protagonist's childhood friend being raped and murdered). Even people who liked the idea of an anti-isekai plot were generally turned off by the story playing too many tropes that make the genre contentious straight. Needless to say, Cheat Slayer only lasted a single chapter before it was cancelled in the face of massive backlash.
• Complete Monster: Louis Crawford, "God's mistake", is a perverted sadist who believes the new world exists only for the amusement of reincarnates. As a member of the corrupt Rebels Against God, Louis uses his cheat powers to kill random people and rape any woman who catches his eye. He destroys Lute's home village and rapes his friend Lydia to death, almost killing Lute in the process. When he encounters Lute again, Louis tries to kill him again to Leave No Witnesses to his crimes.
• Hilarious in Hindsight: The comparisons to Garth Ennis' The Boys are even more fitting if you know that The Boys actually got canned fairly early on its run (6 issues in) over the anti-superhero overtones of the work^note The comic was originally published by WildStorm, a now defunct subsidiary of DC Comics. Ennis bought the rights to the comic which allowed him to continue to work on it once it was picked up by Dynamite Entertainment.
• Overshadowed by Controversy: Everything about the manga's plagiarism and poor attempts at parodies has completely overtaken the knowledge of what the plot of the manga even is, especially since it was notoriously cancelled after only one chapter was published.
• Shallow Parody:
  • Much of the reason for the swift cancellation seems to have been this trope; it seems as if the writer did very little research on any of the stories involved, instead treating them all as if they filled the mold of "Stock Light-Novel Hero with a cheat skill popping up in a Standard Japanese Fantasy Setting that operates on video game mechanics and having an adventure that is little more than a naked Power Fantasy." The problem is, most of the stories parodied don't actually fit that mold (taking place in a more unique setting, not featuring a Stock Light-Novel Hero, not using RPG mechanics, not featuring a protagonist with any kind of special power, not featuring any significant action). In fact, most of them became popular in part because they didn't fit that generic isekai mold, and two of the ones that do fit it (Konosuba and Re:Zero) are a parody and a deconstruction of the concept, respectively. This causes most of the critique involved to fall flat; it would be rather like doing a Batman Parody that complains he's unrelatable because he has superpowers. If the parodied characters were instead like Yuuto Suou or Touya Mochizuki, much of the controversy and plagiarism issues would have been avoided.
  • The main parody involved in the first chapter is Louis Crawford, a Corrupted Character Copy of Shinn Wolford from Wise Man's Grandchild—depicted as escalating the standard isekai harem romance and the attendant latent sexism into him being a rapist and sex maniac who threatens two girls to blow him at once. The problem is, while Grandchild plays most isekai tropes straight, it's notably not a Harem Genre series like most isekai stories; the main character has a pretty gender-neutral friend group of which only one girl (who he's in a relationship with) has feelings for him.
  • Members of Rebels Against God are described as having been loser NEETs in their past life. While this is in fact common among the Stock Light-Novel Hero, out of inspirations of the nine known members, only one had such a past life^note Subaru of Re:Zero, who was a Hikikomori. Three of them never reincarnated in the first place^note Aqua, Aletta, Kirito, three were salarymen^note Tanya, Ainz, Shin, one was a middle-level manager^note Rimuru, and the last one was an Ordinary High-School Student^note Catarina.
