Thank you all for the show recommendations
Firefly
Honestly? With the benefit of hindsight, I’m actually pleased it wasn’t given the chance to become a Dollhouse.
The movie gave closure, and we left the characters in a good place.
Dollhouse gave us 5 seasons of content in one, and ruined itself in season 2, and many other shows have just run until everyone was sick of them, before getting an anticlimactic ending anyway.
