Orphans, Orphanage in children's movies and books?

If you are a member of the adoption triad you probably know of Disney's need to kill off a parent in every movie. We avoid any movies that I know have a negative adoption message.  

 I am more interested ( at the moment) in the use of casual use of orphan/orphanage dropped in movies, books etc...  How do you handle this?  

My son LOVES superheroes right now.  Loves!  One of the stories I read to him starts off with 'blah blah blah...didn't come from the best beginnings.  He and his brother were in an orphanage when they were little....'  Do I read this to him or skip over it?  I'm torn.   

Would he view this as empowering-knowing one of his beloved super hero's was adopted?  Superman and even Word Girl came to this planet to be saved from some disaster.  Hawkeye and his brother were in an orphanage.  Even Spidey is raised by his Aunt and Uncle.  Hmmmmm?  Thoughts?
