Which was really really lame, especially with how they did it. Season 2's ending was a complete mess, I had no idea what was going on tbh.
Why it was a mess is no mystery, though:
1) A need to address the complaints that this wasn't yer granddad's Trek: every show has had to backpedal in that respect, ultimately becoming "canonically compatible".
2) A need to kill a sudden extra hour, when a single-parter turned into a two-parter in mid-production.
3) A need to tie up loose ends that weren't the doing of the current set of writers; weren't necessarily even understood by the current set of writers; and certainly had been the bane of the current set of writers ever since the writers (well, the showrunners) were changed early in S2, and were apparently told to alter many basic premises.
Nothing good could have followed from all that, but at least we got two more hours of Trek to talk about.
The reset button thing wasn't all bad IMHO: Spock browbeating his bosses on what to do and what not to was fun, even if many of his recommendations were idiotic, and Number One dodging and weaving was a fun part of the collage scene, too. But really... The heroes were flying Starfleet's greatest secret weapon, operating S31's greatest secret weapon from aboard her, and fighting an enemy nobody outside the hero circles even knew about - so making all this
remain secret shouldn't have required any extra effort. And the Sarek family not discussing family matters is another matter hardly warranting of an all-new doctrinal decision, and indeed would have been one of the most classic Trek features to begin with!
