The title says it all, it is an extremely bland and generic power fantasy that follows the same tropes as that of an Isekai anime. The anime/manga/LN don't bring anything new to the genre and there's nothing in this that hasn't been done by other media of the same genre. The reason for its hype is that its extremely simple to watch where you can just turn your brain off and enjoy the fancy visuals without giving any real thought to the story. There is little to no character development and the story falls off after the first 50 chapters. When speaking of character development, we need to clarify that getting stronger does not equate to character development. The only way we see JW developing is by getting stronger, there's no real motivation and no real purpose for him fighting. His only real character development comes in the first 60 chapters and then it just focuses on him getting stronger. Like I said its a piece of media one can enjoy if they only turn their brain off and don't focus on anything. Extremely mid and overhyped, boring world building, extremely basic character development but excellent art style.
