The Story: 10/10
Absolutely solid, it flows extremely well and is probably one of the best adaptions of a LN into a Manhwa I've ever seen.
The story is filled with plots that make sense, flowing with extremely well written character development, assisted by very good character interactions.

Of course, like many stories, it starts out slow. When I first started reading this story definitely pissed me off to the point that I was like "Does this even get better."
Yes, yes it does.
You may be annoyed with the MC and many supporting characters in the beginning but that quickly changes as the character begins to go through a change no one in this fantasy world has experienced before.
He is able to level up his rank. Through that experience he drastically changes in personality and is able to experience much more action than previously before, at the bottom of the barrel.
This manhwa quickly becomes exciting to read and you'll continuously be asking for more after finishing each chapter. Give it a chance and run through the chapters, I'm sure it's something all action and fantasy lovers will enjoy.
Art: 10/10
This is where Solo Leveling shines above all it's competitors.
What starts off as mediocre art suddenly improves drastically to become pure joy to look at, I've never seen manhwa done so beautifully.
It's so unique you can't really compare it to art you see from something like OPM for example. Each panel is a sight to behold and truly makes you appreciate it on a whole other level. Keeping in mind it's released on a weekly basis which is unbelievable.
Enjoyment: 10/10
In every aspect this is a masterpiece to behold and I urge you to give this a fair chance, you will not be disappointed, I guarantee it.
Overall: 10/10
A Masterpiece, I say It is just mind blowing .I can not wait for the this manga to continue.
