As egrets mentioned, it is more sci-fi tech rather than realistic tech. I don’t think it is extremely unrealistic as a proposed idea, but it is something that could never work at the scale shown in the show. In a weird way, the end of the show felt to me like it got both more realistic and more unrealistic. I’m trying not to spoil anything, but I hope that can give a bit more info to decide if you would like it.
I don’t think it is very well known, but I thought Scavengers Reign was very good. It was a bit slow, but I thought it gave time to see the weird alien world.
If you are on the fence about it, the show is a followup to this short and has some similarities in its world building.
