Trying to arrange my thoughts on this opening episode:
Overall:
I friggin' loved this episode. Though I probably wouldn't recommend it to someone only vaguely familiar with Trek. Unlike, say, "The Mandalorian" which could be viewed without any backstory knowledge, this one requires a basic understanding of (TNG) Trek. Not surprising since it's a direct sequel. But I do think the introduction to a lot of the worldbuilding/backstory could have been made a bit more newcomer-friendly.
For me, as a hardcore Trekkie though? Fucking fantastic. I immediately felt familiar in this world. This was an amazing mixture of the fast-paced, emotional JJTrek-style with it's bombastic vfx. But applied to the more slowly, thought out and familiar TNG-era world. I like that the universe wasn't at war, a straight up dystopia, or on the decline or anthing. Instead a very good depiction of un-easy times, following tragic, monumental events.
If SF oftentimes is a depiction of the era it was made in - this one got it right.
Main Plot
Frankly, this is the part where I can comment the least right now. I have to see where the plot leads us. I thought the demise of Dahj was a bit cruel, and felt more like "modern streaming show conventions" creeping in for the "surprise!"-effect on viewers. But it was an extremely effective hook (the twin thing), and searching for the twin is a good narrative thread to build the next few episodes around. We'll see where it ends.
Characters
Probably the best thing about this show. I like they didn't "Old Luke" him, he wasn't entirely crushed or defeated. But not a perfect fairy tale ending either. It felt very natural and realistic, the way the Picard we know would handle a personal defeat. Go to retirement. But always ready to come back on his own, if he feels he can change something for the good. His heart never stopped burning. That's great to see in an older, fictional character.
The entire cast was amazing, to be frank. Dahj's actress was capapble of standing her ground to Patrick Stewart. That's not a small feat. I hope she stays around. I really love Allison Pill's robotics/A.I. expert. She was down to Earth, likable, relatable, damn good role model. And goddamn, do I love the older Romulan refugee couple, they're the perfect characters for Picard to play off of.
Worldbuilding
Again: This episode just got it right. I really like how it retconned ST09's supernova to be both more scientifically accurate, and still weave a story around it that also fits in the universe of TNG perfectly (the tried but failed rescue attempt, the political ramifications, refugees, unease society such a massive event would create). That was handled beautifully.
I'm a bit worried about Mars, and I think it was a bit difficult for people who haven't watched Trek in a while to get into the whole backstory of TWO completely bonkers, completely unrelated, planet-annhilating events at the same time. I hope this will be further explored during the season, giving us more details of the backstory. Right now, it's a bit difficult to grasp all the information. But the way it was presented through it's ramifications (empty research stations, Romulans on Earth) was pretty great and convincing.
Final words
I love it. We will see where the main story leads us, and what I will think of that. But right now, it feels like "my" Star Trek, the one I fell in love with, is back. And I'm more of a TOS guy!
If they make new future Star Trek series, I want them to be set in this exact same universe. Just tell their own stories with their own characters within it. In the future, I want to see even more new characters, unknown aliens, spaceships, and plotlines that don't require any previous knowledge. But for what it is - a continuation of one main charachter's storyline in this universe, dealing with the big events of his life - this is starting out perfectly.
10/10
There is still room for improvement on the details. But for what it is, I'm truly amazed at what we got in the first place.
