Does anyone else have issues with the movies being released that have adoption themes?

Does anyone else have issues with the movies being released, that have adoption themes. We took our 3 year old to see tangled, dispicable me, and Kung fu panda 2. The first and second movies portrayed the adoptive family in a bad light, the last the birth family. I am fine with movies that have an adoption theme, but why do they need to add lines like “your family didn’t love you so they gave you away” ect? When we do go we address any questions she has, but I wish they would look at what they are saying.
