It feels like the creators of Nightflyers were trying too hard to create something unique which sadly resulted in a mishmash of different themes/concepts that didn't really work well with each other imho. While the first few episodes were quite promising, the show slowly disintegrated into singular fragments. Towards the end, it was just too much of everything and it often felt like there were parts missing inbetween episodes, as if they cut out several scenes.

One could argue that the way the last few episodes are constructed, it mirrors the emotional state of the crew - but it also takes away from the experience. I can fully understand why some viewers felt confused, the writers could have done a much better job with the material at hand imho since the entire premise has a lot of potential. But with the final episode, I'm not sure what else there is to tell since they have basically used up any possible twist material already.

Overall, the show does provide food for thought regarding its main theme but sadly doesn't offer many answers or insights and only scratches the surface regarding the various themes/concepts it presents. Thus, it doesn't bring anything new to the table thematically and even with their attempt of a different approach, Nightflyers disappoints with shallowness.
