Are you saying that Marvel is wasting its time with the Marvel Adventures line.  That none of these readers will grow up to buy comics. None, Zero, Nada.

Kids are reading comics with Marvel characters.  When they get older, the book stores will have trades of the existing Marvel universe they can try.

I don't understand some of the negative attitude towards the Adventures line.

I just happened to be checking out a preview of the new Moon Knight, and just to illustrate a point about Marvel and comics in general, particularly from a writing standpoint:

Aside from the ridiculous overuse of cursing in comics, as seen here, this fight scene which is NOT being spoiled, has a reviewer pointing out how violent and vicious the fight is. Well, it is vicious, the two are trying to kill one another.

But then, at the moment Bullseye gets the upper hand, with the knife, he decides to...talk about it!!!

Ye gods, man. Either stick with the superhero comic unreality or lose the viscera and cursing trying to make the comic "adult."

As a parent of two young regular readers of comic books (Marvel, DC and Indies) there is a lot on that list that my boys are looking forward to reading. At this point the 5 year old prefers being read to as opposed to the 7 yr old who is reading on his own (and reviewing) but he's picking up:

Amazing Spider-Man, Spider-Man Family, Deadpool, Iron Man, Marvel Adventures: Avengers, Mighty Avengers, and Ultimate FF. That's a pretty healthy haul for one company and one week.

And the thing is, with the exception of a few titles they usually read comics based on a cover and flip through. They've picked up stories in the middle of a run (like Secret Invasion) and loved it and had no problem figuring out the story. They like what they like. I think a lot of times we sell our kids or kids in general short on what they can handle/comprehend.
