I agree with you completely. Retelling the same stories is lazy, and giving into nostalgia for the sake of nostalgia alone is shallow. I don’t see either of those things in Picard so far, though. It seems to have what looks to be its own story, a fresh take, that very much flies in the face what’s come before. But it does so largely without ignoring what’s come before. In effect, Picard connects with the universe we’ve seen before, and thereby gains agency to challenge that universe. By contrast, Discovery was intentionally designed to look different from TOS and TNG and all the other series, and as a result, no matter how thought-provoking it may ever be, it will never (it can never) challenge anything about TOS or TNG. At least, no more than BSG or The Expanse or any other sci-fi show. They’re different universes, and when I watch them, I’m only vaguely aware that Discovery is trying to say something about the shows I watched before, that I could (and probably should) be potentially be re-evaluating through a modern lens. So yes, I agree about the virtue of being challenged by the story and it’s evolution. But to my mind, the only thing Discovery can challenge is itself.
