Manga, on the other hand, are mostly independent of one another, and that works to their advantage. If I want to start reading Naruto (unlikely), I can go back and pick up issues 1-however many of Naruto, and with a day and a half of reading, I'm all caught up. I don't have to have read issues 3-5 of One Piece, 9-12 of Death Note, 29 of D.Gray-Man and 73 of Bleach in order to know what's going on. Graphic novels are similar in that regard. I know what I'm getting, and it's easy to get it all. That's all I'm asking for, really.
The comic book format is solid, there's no denying that, and when used correctly it tells a story just as well as any other medium. However, if appreciating the biggest titles, the ones everyone knows about, require the kind of encyclopedic knowledge only a loser can accumulate, ALL comic books will naturally be shunned as the sole domain of those losers.
