Demon slayer is a sorry excuse of an uninspired battle shonen and a perfect example of how to not write a story.
you probably know already how the story goes so I'm gonna skip over the brief summary
Let's start with the pros
- Great fights
- Cool power system
yeah that's pretty much it
Moving on to the cons
- Uninspired side cast
- basic story
- Boring protagonist
- generic character design
- horrible artwork
- lackluster villains
- undiscovered world building
- Generic concept
- Awful comedy that happens far too much
- repetitive formula
Overall:
Demon slayer is a generic and uninspired battle shounen that doesn't deserve the hype it gets, the story is repetitive, the side cast is annoying (at least for me), the art looks like a coloring book, and the villains suck. Not worth your time, there are far better battle shounen that are similar.
