Tense but unanswered questions

Rating: 8/10 (11 November 2019)

It is a good film in that it is very tense but it would have been worthwhile to put more background into the story line. Where did the creatures come from? I can't really see blind brutal monsters utilising interstellar travel.
I can only think there will be a prequel and a sequel. A prequel for explanation and a sequel to see if the creatures can be defeated.
That said, I though the acting was good and there was some character development albeit not as complete as I would have liked.
