I don't believe Trek needs time off. I believe what the Star Trek franchise needs is people who know how to tell good stories, put those stories into a teleplay, and then get that teleplay onto the screen.
From what I have seen, most of the recent stories for Enterprise have all been stories created by Berman and Braga and then pounded out by a staff writer. They shy away from strong choices, and go with the old and tried...which comes out as old and tried.
Enterprise has a lot of potential, but all of that potential is being buried in a vat of decontamination gel.
Berman and Braga need to step back a few paces, and let someone who can tell stories, who can write stories, and who can put those stories on the screen in a new, fresh, imaginative way.
If they can't step back, then I have a feeling that Trek will die.
Quack!
