It's funny ... I liked the episode more than I didn't, but most of my problems with it are the ones that a lot of the critics of Picard season 3 had with it. A lot of the moments in the beginning felt like forced nostalgia moments.
Remember when they stole the Enterprise in Search for Spock and now here's Spock doing it? Remember Spock played a musical instrument in TOS and here's how he started doing it? Remember how each captain has to say something different when they go to warp?
And there's some weird moments here too ... like Captain America's Super-Soldier Serum exists in the Star Trek universe? The entire slow-mo sequence with M'Benga and Chapel felt like the writers got to the part of the story where they needed to write a way for the characters to contact the Enterprise, and they threw up their hands and said let's just have them Hulk out and do an action sequence.
Also, I like what Ethan Peck has done with Spock, and this isn't a criticism of him or his acting, but I just don't buy that this version of Spock is the same guy we end up with in TOS. The TOS version of Spock always felt like someone that lived in shame among Vulcans for being half-human (an "outcast" per The Final Frontier), had been taught most of his life to shun humanity, and ever so slowly realizes the value of humanity and his own humanity through his time on the Enterprise with Kirk and crew. Strange New Worlds, on the other hand, seems to be setting up that maybe it's things going bad with Chapel or Pike that puts him back into a Vulcan shell until Kirk comes along.
