Star Trek: Strange New Worlds is pretty great, right? It's a prequel series for Star Trek: The Original Series and does a good job showing some great stories of the USS Enterprise before James T. Kirk took it over. The series relies heavily on its relation to the original series quite a bit.
Not only does it borrow from the original show by using characters like Kirk, Spock, Nurse Christine Chapel, Nyota Uhura, and Montgomery "Scotty" Scott, but it also plays off of the original pilot for Star Trek, which featured Christopher Pike, Number One (later Una Chin-Riley) and of course Spock. It's essentially a continuation of that original pilot.
It combines the original pilot (The Cage), the details of the eventual pilot (Where No Man Has Gone Before), and the subsequent series that is Star Trek: The Original Series while combining it with a fresh coat of paint and new characters that fans can get behind. It's molded all of these aspects into one fantastic show. A show that works due to its complex combinations of past ideas.
Yet, it only works because the original series that it's based on didn't fully tell their tales. We know the events coming out of the original pilot were canonized by the eventual original series, so we got characters that were introduced like Pike but gave little to his character and legacy. Same with Una and others.
Strange New Worlds has changed that and has given more detail and weight to the crew that came before Kirk. So it's smart to do a prequel series because it expands on concepts that the original series just didn't have the time to explore.
Which is exactly why the idea of a Star Trek: The Next Generation prequel is so silly. Unlike The Original Series, The Next Generation got a chance to tell its stories. We got seven seasons, four movies, and an eventual sequel series in Star Trek: Picard.
We know all about Jean-Luc Picard's backstory, at least the moments that matter. Same with William Riker, Deanna Troi, Data, Worf and the rest of the crew. What more could be explored in a prequel that we didn't eventually see across 10 combined seasons and four movies?
I know the trendy thing is to do prequels and rehash more popular stories in the hopes of squeezing something out of the IP, but after the abject failure of Picard, maybe it's time we just leave the Next Generation characters alone for now. After all, we don't want to ruin whatever legacy they have left, right?
