The ST universe has so much potential. Would love to see a darker version of ST if they make a new show. Not your usual " explore new planets " stuff that has already been milked.
DS9's last few seasons were just great and a lot more conflict oriented and serialized.
Any new series would need to follow that example. Would be great to see a series where the Federation is at war for the entire run.
Something like " Yesterday's Enterprise " but an entire series like it , and of course , no children on board the starships so we don't end up with any Wesley Crusher type characters
