Reboot

They should make a reboot of Barney for adults who were kids when it originally aired but update it in a way that they would be invested in it as adults. Like bring back Min, Michael, Tina, Derek, Lucy, and Tosha as adults where they discover their old dinosaur toy Barney and they unlock the mystery of what brought Barney to life and journey into the imagination realms to explore the mystery and why Barney chose them as kids to impart his knowledge and possibly even learn where Barney came from. Like what if Barney is like a Buddha of the dinosaurs and he was a dinosaur who achieved enlightenment and immortality and that is how he was able to exist in modern times and use his magic.
