So your boys can't enjoy movies if they don't have a male lead ? Are you living in a barn in the 1950s ?
Oh, boy... my favorite Disney movie is Beauty and the Beast... Now I have to live while worrying I could be called a 'beta male' and a 'wuss' by some internet trolls that see the world the way my grandma does.
I love how you use the weaker animated film Disney have released in the last 8 years as a point. Big Hero ain't bad, but it is surely not a deep film. The characters lack consistency and all can be reduced to a single character trait, the scenario is predictable and don't have a real deep meaning (except maybe "use the robot your brother designed to save thousands of lives to become a superhero and save some lives in your city here and there"). Ralph, on the other hand, has a powerful, strong message that kids need : sometimes in life you fight hard for something, want something, and yet you won't have it.
