Flawed but thoroughly entertained by it

Rating: 8/10 (20 June 2017)

I don't think I've ever posted a positive review here - this is a first for me - and I'm posting it in SPITE of my complaints about it.
Bottom line - it works as a horror movie, suspenseful all the way through even if the characters are mostly one-dimensional. I didn't care - the set and special effects and the suspense made up for it.
And while I will not give away the ending, the ending always counts for 1/3rd of a movie's rating for me and I gave the ending a perfect score.
Btw, when you are watching a science fiction movie that is about horror you know you're going to find something to carp about, whether it's sound in space or people doing inexplicably stupid things (2001: A Space Odyssey being an exception). And some stupid choices are made in the movie - big deal, if you always did the smart thing you'd never get a movie made. ;-)
