For Trek to come back to TV it has to go back to its roots. Wagon Train to the Stars, Horatio Hornblower in space. We've seen that it doesn't work on network tv as a serialized nighttime soap opera.
You can have character development without serializing it. As much as I loved the DS9 story arcs, Trek was at its best when it started fresh with each new episode. Lots of series grow the main characters and still manage to keep each week's plot in a bottle.
That said, I don't like the "reset button" model. You can't severely damage a main character one week and have them be normal the next. You can have the characters face and resolve conflict in an hour without having to explain the next week why they all aren't in therapy.
That's the way TV used to be written. There's no reason why it can't be done again.
