I remember when Star Trek was about "Boldly going where no man has gone before." It was always at its best when it was when it played around with what people viewed as normal and twisted it upon itself to create a moment of self-reflection. Even DS9 with it's high drama and huge story arc managed to do that on a fairly regular basis, because the other factions and species always had their own perspective and narratives that commented on what it is to be human in a subtle manner.
The way this trailer is put together suggests that despite the name of the ship, there will be very little discovering done, and more about dealing with some existential threat.
And one last thing.... WHEN THE HELL WILL STAR TREK GET OUT OF THE PAST? (True fans will know what i mean lol)
