Disney will launch in November 2019 its new platform called Disney +, where it will release new movies and programs by adding its original series, but since it is a new platform it should be renewed allowing its animated series to have 5 seasons, as well as Star vs the forces of evil, Amphibia, The Owl House, Milo Murphy's Law, Ducktales, Tangled, Big Hero 6, etc. It is a new beginning and it would be great to renew after 15 years, providing more rating and giving them the opportunity for the series to last longer. 

Since also not only help to have a great rating, but to get closer to the public and giving more seasons to your favorite animated series.
