After 6 episodes (out of a total of 8), CONSTELLATION, that stars Noomi Rapace (who has been terrific in everything Iโve seen her in) as an astronaut who survives (or doesnโt) a catastrophe while aboard the ISS, only to return (or not) to an Earth life that is confoundingly similar but not identical to the one she left. By the end of episode 6, it seems that there are at least a couple of other astronauts that are experiencing similar things. I donโt know how this ends (slippage between alternate parallel universes ?), but so far it is fascinating. 5 stars.
