I must seriously rewatch this. It was definitely improvement over two-part as far as far as writing and story goes and I definitely like the characters. However I still don´t know why the inmates are acting like if Burnham started the battle (unless they count killing the torchbearer as such) and those spores really seemed like a too much strange idea (or maybe strangely presented). And this whole serialization is seriously troubling for the real judgement. The opinion is incomplete becouse the picture is fragmentarized.
Just keep in mind that the average officer/inmate we saw was not there, and did not know all of the details of what happened. Even Saru did not see what happened on the Klingon ship. They simply heard about a mutineer who got her Captain killed, tried to attack first, and assassinated the Klingon leader just before the war started.
As the old saying goes, perception is reality.
