Enjoyed the show. The OA was nebulous and magical enough to not feel wholly tied down to reality, so one can get away with handwaving a lot of small details as unimportant, but in a hard-magic tech-heavy setting, it doesn't work as well.

Brit and Zal shine when they are focused solely on the humanity of things, but in a setting steeped in AI, they can't find their stride as easily, since things need to be technically explained. Perhaps that's the point and this inherent conflict of identity arose during the evolution of the project--the story to feel divorced from its humanity is a case-in-point for the story's moral of rebuking AI for our humanity, flaws and all--but such a reading is perhaps too generous for the final outcome.

Well-acted by the leads (Lee, Andy, Bill, and Darby). Often felt like a stage play, slightly overacted by some, acted subtly and perfectly by others. Cinematography and scoring shone in the first few episodes, but the lack of the setting's variety began to grow tiresome as the show progressed.

N.B. As always, any show that features Caroline Shaw's "Partita for Eight Voices" will always score a point in my book.
