Trekyards in their spoiler review brought up an interesting question: is the DMA threatening Earth and Nivar a direct attack? Is 10-C attacking Earth and Nivar on purpose in retaliation for the destruction of the first DMA?
Also, is it possible that Tarka's friend is 10-C and 10-C is trying to reach that paradise dimension? Maybe the DMA is collecting boronite so that 10-C can have enough power to transport their entire civilization that is inside that hyperfield to that paradise dimension?
Unless you believe they already know a lot about the Galaxy and its political structure, even then the response makes no sense because in the 32nd Century neither Earth nor Nivar are members of the Federation. Also Book"s ship is not of federation design, and Book's race was never a formal member of the Federation.
As for my take on the episode I give this week an
8.
I actually liked a lot of the character moments have the scene between Burnham and the Federation President. I also like the presentation of Tarka's backstory.
As for the galactic barrier, I guess some Federation history has been lost in the intervening 900 years because Kirk & Co with the help of the Kelvin's safely and easily passed through the barrier, and you would think that Federation history would record that fact, and further that the techniques used to safely rraverse the barrier ( and whatever modifications were made to the 1701 to accomplish the feat), would be known in the 32nd century. And there also was the fact that the SS Valiant also managed to penetrate the barrier to enter extra-galactic in the 22nd century and even managed to re-enter the barrier and make it back to Galactic space without being crippled by the attempt. The captain of the Valiant destroyed his ship to prevent an esper that was affected in the same way Gary Mitchell was from being loosed on the Galaxy.
I was also disappointed that they did a completely different visual representation of the barrier when honestly, the upgrade they did for TOS-R would have worked just fine. One really has to wonder why they feel the need to reimagine the visuals on every single thing in the Star Trek universe even when it's a natural phenomenon that's appeared various times before. I guess this visual effects team really hates TOS.
One thing I still do enjoy about Discovery and kurtzman Trek in general is that they have gotten away from the Berman era trope of the science and engineering depts being able to accurately predict and everything accurately. I enjoyed the fact that no they didn't manage to 5 light-years from the barrier; that there were elements that the sensor scans didn't account for, and that Stemmons couldn't give an absolutely reliable answer as to how long the ship or the shields would last given the situation.
