This is a fascinating mix of interesting ideas and problematic elements. It's very well filmed and acted, and it's a great new(ish) concept they explore. All the deaths are very painful-looking and there's lots of suspense (and a surprising amount of blood). So if those elements aren't really your thing, then definitely skip this one. I was expecting it to feel like a cross between Alien and Sunshine, but it just ended up feeling like The Mist.
