Yes, it's definitely worth reading. It offers a great exploration of the Daredevil and Bullseye relationship. The graphic novel has some amazing art that really brings the story to life. The action scenes are intense and the character development is quite engaging.
Sure, it can be normal. Just like any person might be interested in what others write about them or their alter - ego. It's a way to connect with the fan community on a different level.
I'm not sure specifically as there could be many 'bullseye graphic novels' with different stories. It could be about a heroic character named Bullseye, or perhaps it has a plot centered around a target or goal (as 'bullseye' can imply), with lots of action and adventure depicted in the graphic novel format.
In many tellings of Bullseye's origin, he was an outcast from an early age. He was not part of the mainstream society and had to rely on his own instincts. His origin story could also be linked to some sort of trauma or difficult situation in his childhood that made him focus on developing his aiming skills. For example, he might have been bullied and found that being able to accurately throw things at his tormentors was a way to defend himself. As he grew, he continued to hone this skill and it became his trademark, leading to his identity as Bullseye in the story world.
Well, it could be a way for the daredevil to see how others perceive their character. Maybe they find it interesting to see the different scenarios and relationships that fans come up with in the fanfiction.
