While I absolutely acknowledge that there are people looking to complain about things, that's not at all what this conversation was about: The end of all life in the universe (multiverse) is silly because of the reasons listed above.
Other Treks have had issues with Stakes, absolutely. It was silly when the Enterprise was near earth and somehow the only ship in range. That's a legit criticism of many older Trek stories. If DSC does it, it will be a legit criticism of a DSC.
There is nothing wrong with holding a new show to a higher standard. DSC is standing on the shoulders of giants, so it's great when they do great, and kind of inexcusable when some elements are as well handled as Spock's Brain.
Boreth makes lots of sense, by the by. The degree to which it matches previous continuity... there's definitely room for argument (though I personally like the way DSC treated it).
