Deano’s answer to: “After Captain America, Thor, and The Avengers, will Marvel run out of great superheores for their movie franchises?”

I'd actually take things in a little more hard boiled direction, and suggest Alias as a good comic to screen conversion…
The story of a B or even C list heroine who hangs it up to become a private investigator after being mind-raped by a supervillain… Skulking around the periphery of the rest of the B-list characters (Luke Cage, Daredevil, even Jonah Jameson), their families, and problems. Also shows a lot of depth into "superhero problems" that regular people don't have, but stays very much grounded in a "real world" – powers are firmly secondary to the plot, which just makes it that little bit harder for a movie to screw up. 😉
