One of Sarah's View's

As Sarah mentions in her post she says "Quite simply, mothers are killed
 in today’s kids’ movies so the fathers can take over." Sarah speaks out very
 boldly and takes a light jab at the world in which men are more dominant. Sarah 
could have said, "so that men can have a chance to shine as a parent, who is present." But she instead took a punch at the perception that men rule everything and are now trying to take over another place. 

This is a very broad statement though and the perception that fathers
 can take over is too much. Fathers dont get the amount of respect that 
women get in the world. Children see their mom as both protector and 
care giver and then they look at their dad as a friend more than a father figure. 

Fathers never get a chance to show off and show that they can be kind,
 loving and generous. Fathers arent looking to take over the movies, we are just looking to be seen and heard. Walt Disney's lost his mother and in result only had a father to 
watch over him as he grew up and lived. So this could have drove him to see 
that fathers are left in the back while moms take the credit of caring for children and so he wanted to show off the dads, since he was raised by his dad.
