Hopefully they will not follow a plot similar to one in the 1980s V-the Series with the starchild or whatever she was called.
The thing that happened to ST-TNG that gave it life was when they retooled the Borg into a threatening adversary. The premise of Star Trek is contrary to that--it's about seeking harmony with others--but the Borg (at least in the best-remembered stories) was the unstoppable, unreasonable threat. It allowed for a kind of suspense which Star Trek had not previously had except with Khan (which was also in opposition to Star Trek's harmony theme too since he originally welcomed being put on the wilderness planet--after 20 years he was mad that Kirk wasn't looking after his welfare more closely!).
