What is an important theme in “once upon a time”?

Answer and explanation:

Once Upon a Time is an American fantasy drama television series that premiered on October 23, 2011 and concluded on May 18, 2018 on ABC. It borrows elements and characters from the Disney franchise and popular literature, folklore and fairy tales.

The series is based on the theory that there is an alternative universe where all the characters of the classic fairy tales exist, a world that has a lost connection with our world, so it focuses on the characters of the Enchanted Forest and the conspiracy of the Evil Queen to disturb the lives of the other inhabitants. Through a curse, the Witch sends the characters of the stories to the village of Storybrooke, Maine, where they all live without knowing who they really are, so that she is the only one with a happy ending.
