It's a show that relies a lot more on plot twists than actual plot, and they're the sort of twists that heavily recontextualize the story in such a way that everything that happened prior is rendered kinda irrelevant and thus never followed up on, which kills a lot of the narrative momentum before it even really has a chance to build. There's maybe one halfway-decent "oh shit" reveal followed by a long series of "huh?"s and a big final "where the fuck did that come from?". And by the time it's two or three twists in, anything that seemed unique about the concept gets sidelined in favor of some increasingly credibility-straining political intrigue with token sci-fi elements.

And in general I kinda thought they did a poor job of making the spaceship feel like a spaceship, making the descendants of the Red Scare people feel like descendants of Red Scare people, and making the 1960s Space Race technology feel like 1960s Space Race technology, but in that annoying way where it's clearly not from a lack of budget, just from a lack of imagination. It's all just some very generic people with generic sci-fi technology living in a generic sci-fi city that just so happens to be shaped like a spaceship. And it's one of those shows where the main plot (term used generously) grinds to a halt every couple act breaks so everyone can fuck and backstab each other for no reason other than the characters that aren't part of the plot right now need something to do. And then the whole thing kinda just... stops.

All in all I found the whole thing dull, generic, more than a little frustrating to watch and harder to get invested in the longer it went on. The main characters weren't all that relatable, barely likeable and not particularly memorable; the mystery at the very heart of the premise was handled in a way that made it very uncompelling, and the ending fails to justify about 70% of the story that preceded it.
