Star Trek - It's dead Jim.
It shouldn't be, but it probably is.
The show-runner just don't have the vision, and apparently they can't find good writers.
There are two spin-offs (I had heard a rumor or two) I would have loved to see if done properly.
1. A prequel about the early Federation's first war with the Romulans when they were getting their butt kicked and on the verge of losing. It would have been awesome to do it in old trek tech and uniforms like the first pilot The Cage.
2. A spin-off centered on the Klingon Empire and all the internal intruige and in-fighting and coups.
But it's just as well I guess. The current players would just butcher it.
