All of them seem like no-brainers except for serialization. If they go the serialization route, I want them to do it because they have a great story not simply because everyone else is doing it. Great stories can be told just as easily in an episodic format.
Any new Trek series is going to be serialized to some degree. It's just how you make dramatic television nowadays. The question is how much serialization. I'd like to see any new Trek series be less like Breaking Bad
and more like Mad Men
in that regard.
I'd also argue that any new Trek series should stay as far away from broadcast network television as possible. 22 episodes at $2 million dollars per episode, with the audience that network television attracts now, is a recipe for cancellation.
