It’s okay. It’s a version of the classic “kid thinks parents are ogres and would rather live without grown-up interference” trope. In this case mom got snatched by dragons and dad is lost at sea in a bottle. When an aunt shows up and tries to take over, Clementine invents an invisible paint to hide the house and get rid of the aunt. When she accidentally leaves the door open one day she ends up with a lion as a houseguest and must find a way to make peace with it and carry on in case her parents come back some day. On the one hand, a lot of kids can relate to the living-without-adults fantasy, on the other hand, it seems a bit disjointed.
