Reasonably good. I purposely avoided reading anything about it and had no idea what the premise of the film was before I watched it, as I wanted no presuppositions.
Main niggle was ...
Spoiler:
the contrivance wrought by Tom Hollander's character, in being so normal and supposedly believable as another survivor seeking refuge, yet he was anything but. Felt too forced, too set up.
I did like that you never see 'the creatures' though, and their whole set up was suitably mysterious and enigmatic.
Worth the watch.
