Actually, the animated series back in the 70's did revisit the Guardian of Forever, and one of Gene Roddenberry's suggested stories for Star Trek 2 was a plot involving Klingons using the Guardian to go back in time and assassinate John F. Kennedy. The intentions were there, but it just never happened.kaikatsu wrote: Generally, I hate the fact that so many episodes have really interesting implications, and never get used.

The "crystalline entity" from TNG Datalore made a comeback, though. As did Professor Moriarty. Minuet from TNG 11001001 made a bit part return in TNG Future Imperfect. The clone from TNG Second Chances returned in DS9.
Yes, there's plenty of hanging threads that would have been fun to revisit, but it's not as if none of them ever were... and, to be fair, it's not as if the very same starship crew would necessarily always be the ones to come back to their old problems.
Did you just call TNG the "original Star Trek"?This might be a point of contention, but I tend to dislike one episode wonders. The original Star Trek had a lot of that -- an interesting new idea or planet that is ignored for all future episodes. I mean, the Dyson Sphere. The DYSON SPHERE! There could have been an entire SERIES based on the exploration of the Dyson Sphere, trying to unlock its secrets, or find out who made it. (Ringworld comes to mind.)
Get out.
