This is a review for the whole season, not just one episode. Each of the episodes are pretty equivalent to the others: good enough to keep watching, not great.
Brie Larson is a good lead character and talented actor but the story overall is too mawkish and "pat." The overall theme is, the 1950s were misogynistic and racist, and the good, noble characters fight the good fight against the bad characters, who have no depth and are simply cardboard representatives of the patriarchy, whose role is to stand there, sputter a bit, and then be defeated, by a puzzling deus ex machina as it turns out.
The production design is very good, reminiscent of Mad Men, a series that tackled all the ugly aspects of the era without turning it into a hectoring soap opera.
The way it ends doesn't really set up a season 2, so maybe this is one and done, although who knows. Apple could make a season 2 if they felt like it. I doubt I'll bother to watch.
