"If you Want Peace, Prepare for War"...........well, that's debatable but setting that aside for a moment......
.......this episode gives us a fairly Trekkian away mission to the Blue Planet of the Ethereal Beings of Cosmic Harmony. As a welcome break from the oppressive atmosphere aboard Discovery and the internecine politics of the Klingon ship, it serves its purpose quite admirably.
Three characters: Burnham, Tyler and Saru get to run around in the fresh air, build a shelter and communicate with some weird floating alien things while undergoing an essential mission. Not too shabby.
Doug Jones gets to add some range to his character as the aliens take him over and influence him to fight the other crew members but I'm not sure that the writers know what they are doing with his character as his courage is so often questioned and he is made the butt of too many jokes.
Whilst the Vulcan's now have their Logic Extremists and the Klingons consider diplomacy an anathema, the Federation is supposed to be tolerant of all sorts of differences. Senior Trekker long since gave up hoping for any narrative continuity with earlier Star Trek series (paradoxically set in the future of this one) but expected some continuity of values.
It isn't just the hyper-realistic piles of dismembered corpses that are making me feel slightly nauseous.
(And on that last point, why do so many commentators overlook all that carnage and references to torture while complaining so bitterly about a couple of profanities?)
