Nice mix of space opera and family drama. All the actors are great and it's pretty tightly written, even has a few lovely little clever surprises (like the subtitled scene in the cave episode). Mixes the episodic and serialised styles of sci-fi shows pretty seamlessly too, so you get a nice adventure/danger of the week interspersed through a longer narrative. It's actually taken me a bit by surprise that I like it so much as I avoided watching it for some reason. Well done Netflix, this is a good one. Looking forward to the concluding season.
