Star Trek: Deep Space Nine ended in 1999 after 7 seasons but didn’t jump into feature films like The Next Generation. Here’s why.
As much as I wish they could all be in a DS9 revival I don’t see why they have to. Sisko ascended, Odo returned to the founders, and it would be easy to say that Nog is just stationed on the far side of the Federation or on a deep space mission. The first two could easily be off screen presences who effect the story but are never seen. That still leaves Bashir, Dax, Kira, Worf, and Jake. Could be a smaller, more personal story that follows up on plot elements from DS9. Like what they tried to do with the first two seasons of Picard, just hopefully better written.
If they hire outstanding writers then I’d be interested in a show about Jake after his dad disappeared. Follow that timeline and show Jake’s struggle. It doesn’t really need to happen though and it would be very high risk.
