Nowadays, every new series or movie is set in a pre-existing universe that dates from the late 80s or 90s. Everything must be part of become a franchise to be funded, even if the team behind have little or nothing to do with the original creators. I do understand that producers want predictability and anything with a established fanbase is much less risky than betting on the next Jurassic Park, but they are simply killing the golden goose at this point.
