Hoooly fuck just finished this and man it's gotta be one of best sci-fi shows I've ever seen. The use of the multiverse concept to explore fate and free will and grief, can't say I've seen anything else like it. Garland's direction is top notch and it's hauntingly beautiful in the way it's shot and the score - sets the tone for the show and every scene so perfectly, simply outstanding.
Thought I would be able to predict where the show was going but love that it kept me guessing at every turn. A lot of shows dealing with such a concept would take the easy way out but love that this sticks with its ideas through and through. Few pieces of sci-fi media treat its adult viewers as adults and love that Devs does that by not stuffing exposition down your throats and expecting you to understand using your brains.
Sonoya Mizuno and Nick Offerman are out of this world and do most of the heavy lifting for the show without missing a beat but god the supporting cast, especially Cailee Spaeny and Zach Grenier among others are so so good.
