To be honest i understand both sides of the coin in the debates on Solo Levelling:

Yeah, it's a banger. You'll finish it in a day and re-read it the next. It's just that fun to read.

The originality and story, however, are lacking. I can see how some people don't agree with the "Hype" surrounding it. It's nothing new, and besides "grinding" the story doesn't seem to be going too far.

Character development is always good, (Spoilers for the next line) he gradually loses his humanity while he gets more powerful. It is a little forced however, as a timid and scared weakling becoming a heartless murderer within 10 chapters is more "character changing" as opposed to "character development"

Personally though, i just love the art style. Simplistic but not lacking, bada*s but not overdone. I was giving it an overall 7 until we met Igris and I fell in love at first sight.

I am now addicted to the hype of Solo Levelling and frequently refresh the page for updates. It's not perfect, people saying it it is aren't right, however it is one of the best, if not the best portrayal of the "Manhwa isekai/rebirth/returner" trope that I've seen. Even if you've read this type of manhwa 100 times Solo Levelling will still probably be your favourite.
