Thing is, as has been pointed out before, the third season of Picard does many of the exact same things that the previous two seasons as well as every Disco season has done, which many in fandom have complained about.
It might just be that people expect different things from different shows based on their expectations with those specific characters and actors. If I go into
Picard season 3, where they've promoted it as a TNG reunion, I'm not expecting "New Coke." In fact, I would argue the appeal for many about season 3 is
specifically because it feels as close as Paramount+ has gotten to Berman-era "Classic Coke."
That might not be the version of
Star Trek that appeals to you or others, but it seems popular with a lot of people. I can't tell someone they're wrong for not liking something. But I can tell you why I liked this and why I think it did well and is winning awards.
You got it all, padded story arc that takes too long to get to the point ...
The Borg reveal is
NOT the story-arc of the season. The story-arc for season 3 is the reunion of the TNG characters and seeing how they've changed and become different. And that happens over the first 8 episodes.
Beverly living a life on the edge of space. Picard meeting a son he didn't know. Riker having to confront how losing his son changed him, and affected both his outlook on life and relationship with Troi. Worf, similar to how Spock learned to have balance, finding a version of Klingon honor that is able to have empathy for others, especially with Rashi. Geordi is now a family man that has to be pushed back into action. And we get a version of Data that is similar to his old-self, but not quite.
The Borg-Changeling stuff is only the MacGuffin that triggers the plot.
A "Mary Sue" character who is instrumental to saving the day...
How is Jack a Mary Sue?
He's not perfect or portrayed that way. And in the end, he gets in over his head, almost dooms everything, and has to have his mother and father come save him
Even the bridge crew being non-entities, which for some reason is condemned on Disco, but loved here.
Did anyone expect the Titan bridge crew to be featured in their own subplots? Especially, in a season where the story has to serve the original 7 TNG characters, plus Shaw, Seven, and Rashi. Beyond that, I thought with what little time they did give those actors, they stood out as much as some of the characters that have been in dozens of episodes of
Discovery.
I think
Discovery gets banged for that also because it's called
Star Trek: Discovery and not
Star Trek: Burnham. And if you like the Burnham character, and think the show is great when everything comes down to her being the center of the action, it'll work for you. If you don't like the character or think sometimes it's overwrought, you start wondering why no one else on the ship is able to do anything but listen to Burnham update them on what's going on.
The only difference is that it was a TNG reunion which seemed enough for the vocal elements of fandom to give it carte blanche on things they have rallied against previously.
Could it possibly be the audience has more affection for the TNG characters than they do the
Discovery and other Nu-Trek characters? That maybe when you like Michael Dorn and like watching Worf, some people are able to cut him some slack when he does something goofy that maybe you don't when it's Stamets.
