One other thing about this and your series is that they are also helpful starting places in talking with my daughter among others.
Cap has been her favorite. However, at Dragon*con it cane out that he might be joining Hydra. That even surprised Stan Lee.
Yea, there was something about Cap being Hydra in the comics recently, but I'm sure it will be explained away somehow.
I can't say for certain, it's been a while since I bought a comic book.
