If we judge the Anime as a series by itself, without leaning on our love to the Webtoon, it clearly doesn't deserve the many 10 stars reviews it was getting.
I'm very glad that other artists beside mangakas are getting recognition, but it's important to stay truthful.
The comics has a complex plot, but the execution is also very important when converting it into an Anime.
The animation of the anime was horrible in the first episode. This, by itself, is enough to discourage many people from continuing to watch. The claim of some people that it's original to the comics is ridiculous, since it's a fault the artist made due to low drawing skills, not something that was done intentionally. Completely okay when it's an online comics, completely not forgiven when it's an anime. The animation improved slightly later but it's still not good, especially the drawings of the eyes. But I suppose it's the best the studio could do with a low budget.
The story itself was rushed in the speed of light compared to the comics. Now I might agree that some things might feel like they were dragged too much in the comics, but they certainly over did it when converting to an Anime. And of course when this happens things get lost in the middle.
The relationship between the characters felt very rushed. Instead of the viewer getting to know the characters over time and the characters getting to know each other and building a friendship everything just happened over two-three episodes. I understand that they were probably on major budget restrictions but doing so took so much of the story's depth and soul.
Also fight scenes were simply cut down. It was presented as if a fight was over with one swing, which made the characters look over powered.
In the comics Rak had from time to time comical scenes, but here they seem to make his whole character comical. One of the things that make him funny in the comics is that most of the time he behaved very seriously, but here most of the time he behaved goofy.
In the end, it has a lot of potential since the plot the Anime is based on is very good, I can only hope that if the series gets more popular, their budget will grow and they'll be able to put more into improving the faults.
