The "development" of Janeway returning doesn't have to be bad or a step backwards. I didn't like it when Worf was back in the TNG setting. I thought he was regressing, especially since he was an ambassador. But it has worked well for the character and the series. Look at how many characters DRG III is returning to DS9; it feels like a regression to me but I'm glad to see my favorite characters in a situation where they can have some well written stories. Is DS9 returning back to the series status quo? Certainly not. Both DS9 and Voyager just crossed lines into new eras where they CAN go terribly wrong but I trust the writers of both series enough to not let us down. On the other hand, Enterprise just ended an era where I think it will lie dead for a long time.
