I would say animation is the safe bet if only there could be an adult action cartoon/animated series. Unfortunately I don't think anyone would watch it seriously since so many people have this stupid notion animation is either for kids or fart jokes. I had a conversation with a friend about this once, about if Walking Dead were an animated series would it still be as popular and successful? We'll need live action for a really dark and mature Star Wars show to be watched. Live action would inevitably would require many compromises.
