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.
But that seems like trying to do a 60s era TV show in the modern era of television, serialization works for a reason, it lets you tell more in depth stories, heck even kids cartoons like Avatar the Last air Bender have ongoing stories. Moving away from serialization would be a step backwards, rather then forwards.
Dukat is considered one of the best star Trek villains ever and why? Because he was a reoccurring villain with his arc, which made him more memorable then the average one shot bad guy that appeared in Star Trek. You can still have one shot bad guys, but the main villain should be a reoccurring character, more characters like Dukat and fewer random evil alien commanders of the week who we never see again.
