Netflix's Nightflyers is pretty good. The first couple episodes are an awkward introduction to the story, and it constantly finds itself dawdling a little too much, but by and large it is an inventive adventure and manages to give some fresh takes on well-worn tropes. When the show eventually finds its momentum, it can deliver some genuinely disturbing sci-fi, and when the last episode rolls the credits, you'll be both relieved its over, and quietly wanting to have just a little bit more.
