Where does this idea come from that the "Prime Universe" would mean stilted storytelling, etc? It's a setting, just like the JJverse. A creative and talented showrunner with a creative and talented writing staff will get great stories out of either one. Do another jump, into the 25th Century, or do another prequel, or whatever.
If we ever get another TV show it will most likely be in the "Prime Universe" unless CBS decides to reboot or do their own split timeline. We're not getting a TV show in the JJverse since Paramount owns those rights. It's always possible that that will change, though.
