Well, first, the art. It has a distinct look that draws you in immediately. Second, the characters are so real in their flaws. They make mistakes, they're confused, just like real people. This makes the story relatable. Also, the plot keeps you on your toes. There are so many surprises that you never know what's going to happen next.
The unique storytelling. It doesn't follow the common narrative patterns. It's like a wild ride through the minds of the characters.
The 'End of the Effing World Graphic Novel' is special because it manages to convey deep emotions and complex ideas in a relatively simple graphic format. It tackles themes like love, loss, and the search for identity in a way that is both accessible and profound. The way it uses color, or sometimes lack of color, to set the mood is also quite remarkable.
