Just plain old fashioned EXCELENT. Really enjoyed all of it, start to finish.
At first I was wondering how come the Emporer seemed to have so few guards on her throne ship, then remembered that Lorca had gassed and killed nearly all of them. The ensuing battle was just glorious. Folks getting disintegrated and stabbed to death left and right. I did enjoy seeing the normally mute bridge crew get some attention even if that meant the unceremonious obliteration of MU Owosekun by Georgiou. Loved Michelle's sword wielding.
Appears Lorca was right about destiny driving certain people together no matter the universe, as Georgiou and Burnham continue their bond in the MU fighting side by side just as they had in the PU on the T'Kuvma's ship. Only this time, Phillipa doesn't die. That was a surprise, having her beam off the Charon with Michael. Lorca referring to her by the nickname "Pippa", was a cute moment even though he was using it in a mocking way.
I'm officially on Team Saru after this episode. I wasn't a big fan of the character (though I loved Doug Jones' portrayal), but he won me over the way he took command of Discovery. And as another poster mentioned further upthread, his referring to Burnham as "my friend" is, IMO, the feel good moment of the series so far.
Gonna miss Lorca. It is a bit disappointing that his surliness turns out to have an explanation. I was hoping that this was just the way the guy was. Regardless, Isaacs did a great job with the part and Lorca will go down as one of the most popular, enigmatic, and controversial characters in Trek lore. With this character, DSC has done something none of the other series' or movies has done.
Speaking of Lorca, how is it that some of the people who complained about his being too much of a "meany" to be Starfleet are some of the same people who are now complaining that he ISN'T Starfleet, but an MU inhabitant? I mean, isn't that what you all wanted, either he gets "nicer" or not be Starfleet, right? I'm confused.
Great ending. How does Georgiou get back to the MU? Is the ISS Disco back in the MU? Where is PU Lorca? Was he killed on the Buran?
Best first season of Trek, ever.
