Comic books have entered the larger realm of fiction, they aren't just for the kids. Making the UU more realistic is the key, it's still fantasy. I've said before, the best writers are the best liars, because all writers are liars. The political themes, the relationships delved into within the Ultimates in particular are not things that really concern the average 15 year old.
And the Falcon already DOES have a falcon on his shoulder, in the 616 universe. In this one, for this character, it does not suit.
And furthermore, E is hardly a kid and he started this site because he enjoys comics, I'm a little older than E, and I joined to discuss the ideas that are covered in the Ultimate Universe, because they are not kids books, they are for anyone who enjoys intelligently written, sometimes amusing literature.
