Is my first time doing a review, also English is not my first language but i hope whoever reads it understand my points.

I think most people that read the webtoon would agree that while the casting and acting of all characters was close to perfection, but the changes done to the characters narrative were really bad, the comic was Hyun's fight between his inner demons and his love for his friends and the growth of all of them while being in the end of the world, while in this adaptation i didn't feel most of Hyun struggle nor his triumph against his own mind, his relationship with most characters felt like something was missing and the changes to some of the characters felt pointless, if you are gonna change them is to make them better, but aside of a couple characters, almost everyone changed for the worst.
If this was a completely original drama it would have been a lot more enjoyable, but being an adaptation it was impossible for me to not compare them both, it felt worse than the original story.
Don't get me wrong, i still enjoyed it and think it was a good drama so i still recommend people to watch it, but you should keep in mind that if you got the time maybe reading the original comic will give you a better product.

P.S: Also I'm really annoyed about the overuse of Warriors, who the hell thought it was a song appropriate for the scenes it played?, it ruined my immersion in key scenes.
