It’s a rare film or television show that appeals both to young children and to adults. Endlings (Hulu) is one such show. It’s excellent.
Set in the near-future, the show tells the story of a man who cares for four foster children, each with a unique set of problems. This is the thread with rich themes of building family and dealing with loss that will keep adults as well as children interested. The second-layer story involves a space alien who travels around the galaxy picking up the last surviving members of species heading to extinction. In this future, elephants are in big trouble. The humans and the alien join forces to save exotic animals (mostly escaped aliens) and to thwart the meddling of a woman with darker motives.
The production is high quality, and the acting is consistently good—especially that of Neil Crone, who portrays the foster father. I genuinely enjoyed the entire series (two seasons), and I felt good letting my six-year-old absorb its thoughtful and positive messages.
