This episode started out so well. After last week's fluffy (but very fun) episode, going darker was a good call. We haven't seen a lot of war stories from SNW, just vague hints that some of the characters have some terrible experiences in their past.
Focusing on the two medical characters, M'Benga and Chapel, was a good call. Instead of seeing Starfleet soldiers, we saw what it was like for the field doctors to have injured people beaming into their MASH unit in overwhelming waves.
And we got more hints about that green liquid M'Benga had in a previous episode, which confirms my suspicious about it (not sanctioned by Starfleet) and implies it could be put to interesting dramatic uses in the future.
However, they blew it with the ending. No spoilers here, so I'll be vague and just say the ending does not synch with the notion that Pike is a competent leader who would not shield one of his people from a suspected serious crime. Una, okay. She was clearly being oppressed but this is different.
9 for everything leading up to the ending, 5 for the ending, works out to a 7.
