2. Serenity
Im sort of cheating a bit here but I dont hear you complaining. Serenity was obviously based on the amazing-but-cancelled Firefly by living nerd god Joss Whedon and has since become a cult hit. Whedon created an incredible sprawling universe with tonnes of backstory and interesting characters - perfect for an animated show. While you could quite easily follow another crew of Browncoats on their journeys through the verse, why would you want to? If were not getting another live action series then Ill be damned if Serenity: The Animated Series doesnt star Capn Tightpants and the rest of the gang. Get Whedon, Tim Minear and Jane Espenson on board as script monkeys and youve got a recipe for an unmissable show that kids and adults will love. The main caveat is that it must be set before the death of a major character (you guys know who I mean and I can already hear you weeping) because hes irreplaceable.
