I wondered about that and I'll share here, an excerpt of something I wrote on my personal blog.  My nephew is a great kid, but i tried to get him into comics and he just doesn't have any patience.  He's going to be 13 soon, and he's über literate and intelligent, but he must have ADHD, or maybe he just prefers his tech and sci fi in movie form.  He won't even watch anime, yet he loves the new Batman movies, and i took him to see Doomsday when it came out and here I am, this 31 year old guy high 5-ing his 12 year old nephew during ultra-violent scenes!  Anyway, here's a quick blurb from my blog http://1fed1dead.blogspot.com

"I usually spend about $50-$150 on comics about quarterly. On Sunday I went to Everett Comics on the way to see Bauer who's stuck in the hospital, I got him some cool zombie shit like Walking Dead and Zombie Tales and some more traditional Marvel stuff like Thor and Deadpool. I found this online and it reminded me how much I love comic art. It's obviously a promo-piece for Marvel's 3 most recent successful superhero movies, meant to get kids interested in seeing their heroes on the printed page. But it's cool. I'm glad traditional paper comic books aren't dead. It seems the reason that is true lies with people from my generation though, in the 25-45 age range. My nephew is going to be 13, and he loves tech and movies and stuff, but he simply doesn't have the patience or attention span for "real", ie:old school comics."
